If you think that we will run out of energy if fossil fuel is depleted, you would like to browse this article.

Fossil fuel is non-renewable energy, that means it can run out each day in future irrespective of how much it’s below our earth’s crust. However today we still heavily depend upon fossil fuel as our major energy source. We use fossil fuel ( petrol, natural gas, coal ) to come up with energy, for transportation and making several daily-use product ( plastic bag, nylon, PVC and etc. ). Can you imagine what will happen when the fossil fuel is exhausted?

We tend to cannot drive to work; cannot watch tv, hear music, cook, online, light up our house at midnight and etc. This is because we won’t be supplied electricity if no a lot of fossil fuel on earth! ( how to come up with electricity as our power plant relies on fossil fuel to control? ). Maybe you think that such every day will not exist, however let me tell you: “Petroleum and natural gas can run out in but 50 years time and coal can run out in one hundred years time”.

Once talking about fossil fuel and what will happen if we tend to are running out of fuel ( therefore-known as energy crisis ), let us go straightly into our topic nowadays, the renewable energy. Normally, renewable energy sources like wind power, tidal power and hydropower is used to get electricity.

Firstly, allow us to talk concerning wind power. You will see array of wind turbine lying on a good area. Wind turbine is big and is made very high from the bottom therefore that it will convert energy of wind to helpful kind of energy effectively. How it works? Wind is the moving of air that carries a heap of energy. Wind turbine may be a machine which will convert the energy of moving air into rotational kinetic energy of wind turbine and hence generate electricity.

Like wind power, hydropower use the identical theory as wind power however hydropower convert the energy of moving water into electricity. But tidal power could be a bit complicated compare to hydopower although each of them convert energy of moving water to electrical energy. A reservoir is made at the seaside that have very high tide height ( >5m ), a valve is employed to regulate the water flowing in or out of the reservoir hence is used to come up with electricity.

The most usable type of renewable energy is solar power. All of the renewable energy mentioned above will solely be used to get electricity. Solar power is completely different from the others, it can be used to heat up our home, water and even will be used to cook! And positively, it can be used to generate electricity by using PV cell. PV cell could be a flat panel that uses photoelectric result to generate electricity.

All of the higher than renewable energy are clean, bring no pollution and global warming. There are more blessings using renewable energy than non-renewable energy. Therefore additional analysis and development ( R & D ) ought to be carry out to maximise the usage and potency of renewable energy. Also, may renewable energy can fully replace fossil-fuel as soon as possible thus that several environmental issues ( world warming, pollution…) will be solved.

Your son or daughter comes home from faculty with queries concerning energy. How do you begin to elucidate such a vast concept? Teaching kids regarding this subject starts with conveying that there are various sorts of it around us and even inside us. Life as we tend to recognize it wouldn’t exist while not it. This force is so necessary that each one food packages list Calories, an previous energy unit. Energy is either stored or involved with motion.

The property of an object or a system (a cluster of objects) that enables it to do work is called energy. You wish it to do work or to use a force across a distance, meaning to move something. If it does involve moving an object, it is known as kinetic. A ball rolling downhill has kinetic energy. It will additionally come from the position of an object or its arrangement. This type is named potential or stored energy. A ball that is stationary on the slope of a hill before it begins to roll down has what is known as gravitational potential energy. Because the ball rolls downhill, the potential force it had is changed into kinetic. That’s an example of the law of energy conservation; it can’t be created or destroyed, it changes form from one type to another.

Since it will change from one form to a different, generally it is troublesome to see whether or not it’s potential or kinetic. It can even be potential and kinetic simultaneously, like thermal energy or heat. Even a moving object will have both potential and kinetic at the same time. As the ball rolls downhill, it changes from potential to kinetic. As it rolls, at any specific time, the full amount of force that the ball has will not modification; the law of energy conservation holds. This sort is considered mechanical energy.

When teaching children concerning energy it is important to relay that besides the motion of objects other varieties of kinetic energy include radiant, or lightweight; radiant heat; acoustic, or sound; and electrical, or electricity through wires. Other types of potential energy embrace electrical energy stored during a battery, chemical, nuclear, magnetic, and solar; all stored in atoms or molecules. Elastic energy is potential energy at intervals a fluid or solid that can turn into mechanical.

Will there ever be a perpetual motion machine? That is, a machine that never stops moving and constantly creates its own energy because it works? Most machines noticeably heat up as they operate. This heat is from friction. The energy that goes into a machine is always larger than the amount of labor it produces, because some of the initial energy changes into friction. As a result of friction isn’t utterly eliminated, the energy going into a machine is usually visiting be larger than the machine’s output. A machine will never run indefinitely, so a perpetual motion machine cannot exist.

When teaching youngsters regarding energy you’ll make a case for the different types. It is either kinetic, involving motion, or potential, that is stored. It even changes kind from one to a different, leading to the law of energy conservation. It can’t be created or destroyed, it transforms from one kind to another type. A perpetual motion machine cannot exist since such a device would counteract the law of energy conservation. Energy is a fascinating and vast subject but by remembering these basics, teaching youngsters regarding energy will be straightforward and fun.

After we talk concerning renewable energy, normally we have a tendency to can relate it to the facility from sun, or higher called solar power. However, different than the sun, wind is another supply to get renewable energy. Let’s explore how will wind power work in generating energy that can be used to switch the non-renewable fossil-fuel energy.

Back to the basic, the wind power is truly a kind of solar power as a result of the wind is generated thanks to the heating result from the sun. When the sun heats the world’s surfaces at different speed on sand, water, stone and numerous sorts of soil, these surfaces absorb and unharness heat at totally different rates, making different temperatures. At a sure temperature, the warmer air begins to rise from the surfaces terribly quickly as a result of it’s lighten than the equal volume of cool air. Because the results, the new air rises and reduces the atmospheric pressure close to the world’s surface, that draws cool air to fill the gap the new air leaves behind. This action causes air movement or is referred to as Wind.

Based mostly on the physic theory, when the air moves, it generates kinetic energy, a sort of energy created with the motion of mass. With energy conversion technology, we tend to will capture and convert the kinetic energy into other types of energy such as electricity. Energy from wind could be a renewable energy that can be generated endlessly. It’s become the longer term trend because the one in every of major power generation sources besides the solar power. The globe is put a great effort to create wind power a long-term energy strategy to provide electricity, mainly thanks to the wind power generation is clean and most significantly, it is renewable and setting friendly, a stark distinction to ancient power plants that depend upon fossil fuels.

A wind power system consists of wind turbine, which is made of tower, blades and a nacelle, a management gearing system. The wind power generated from a wind turbine is determined largely by the length and the design of the blades. The look of blades creates a pressure of difference in wind, high pressure at one facet and low pressure at the opposite side. The pressure distinction between the edges of blades rotates the blades. The rotation of blades generates kinetic energy and being transferred into electric energy, is in turn transferred into electricity via transformer.

With the technology improvement that leads to a better generation techniques, the value of generating electricity from wind power has been greatly reduced, making it a feasible renewable energy solution to be used as the main source of electricity for future. After all, there are various homemade wind power system building guides on the market that give steering to people who are inquisitive about implementing renewable energy system at home to form a homemade wind-power system to come up with electricity for home uses. The renewable energy generated from wind has began to become another energy supply from nowadays, and it will definitely be the most important sources for future, replacing the finite fossil fuels as the power generation source.

Outline

Wind power works to generate electricity by changing the kinetic energy captured from wind turbine to electrical energy via transformer. Wind power is clean and renewable energy that will become the long-term energy strategy for the world.

It appears like the crusade to see the simplest various energy sources are seriously being looked into by lots of nations including most Yank cities. One validation is the signing of the Kyoto Treaty. The first purpose of the involved cluster and individuals is to decrease the greenhouse gases and pollutants.

These renewable energy sources have demonstrated to be of great aid in reducing the number of poisons, which are by-product of the consumption of energy. These sources conjointly preserve most of the natural resources that individuals use as resources of energy. As an example, when a solar panel converts the sun’s rays into energy, the sun can still shine for someone else to use. What are the most common sources of renewable energy? Here’s a list to administer you some basic info:

1. Solar Energy – Harnessing the sun’s powerful energy is unquestionably not something new. Capturing the radiant light and heat from the sun has been practiced since ancient times. Since the speedy evolution of technology, we have a tendency to are currently ready to lure the sun’s rays into solar cells. Since the 1950′s solar cell technology has been advancing and has come back quite a long way. The method turns the warmth coming back from the sun into electricity. Photovoltaic cells mounted on rooftops are used to heat water using the sun’s rays. The water goes into a storage tank where the facility is stored, prepared for use. But you don’t want all these scientific processes to be ready to learn from solar power. All you actually have to try and do is open the windows and blinds on a nice sunny day to let the sunshine in.

To this point, the main disadvantage of using this supply is that it is limited. You can not use it obviously on nighttime and during days when it’s raining or perhaps on cloudy days. This has been acted upon through solar power stations. However these are too expensive thus there aren’t too several of these stations around the globe.

2. Wind Energy – Another ancient source of power, wind energy has been harnessed by sailors, farmers and designers for several years, even documented as so much back as five,000 years ago. The energy coming from the wind supercharges the blades of the wind turbines. As this happens, electricity is produced through the use of an electrical generator. In the old days, windmills were created thus that mechanical machinery may perform physical labor. This includes the pumping of water and crushing of grains that were essential in planting and farming.

Currently there are large scale wind farms that manufacture electrical currents. The top products are then distributed to national electrical grids and tiny turbines owned by people to distribute electricity to way flung areas and homes. There are various advantages of this sort of power. The most one, of course, is that this does not manufacture any by-product that may be harmful to the environment. And we have a tendency to will never run out of this supply of renewable energy. One of the main disadvantages of wind power is that it’s never a continuing speed or direction, thus wind turbines should be able to move with the direction of the wind.

3. Geothermal – Geothermal energy is energy obtained by tapping heat from the world itself. Holes are drilled in certain regions, magma and radioactive decay that may be found beneath manufacture steam. This steam is purified and used to drive turbines. These turbines then become the power source for electrical generators.

The downside to geothermal energy is the actual fact that it is expensive to make, and to make sure that no harmful by-merchandise are visiting be produced in the process, geothermal plants must be created accordingly. On the other hand, as a result of the planet’s crust continuously decays replenishing the warmth, it is still a renewable supply of energy.

4. Hydroelectricity – The use of hydroelectric power or maybe hydroelectricity dates back to Ancient Greece and China where they put in waterwheels in rapidly flowing rivers to turn millstones and alternative equipment. Hydroelectric plants today still use the same basic principles as the historical waterwheel, but with some variations. The difference is that we have a tendency to use the force of the water to push the turbine which in flip powers a generator therefore generating electricity. The concept here is to form use of the kinetic energy of water. To form positive that there is a gentle flow of power being produced, a dam has got to be engineered to retain the water. If there is a would like for additional power, the gates of the dam are opened thus water can be released.

There are issues with the use of hydroelectricity. Some claim that it poses a downside for fish and aquatic plants on each sides of the dam. As a result of the flow of water has been altered, the nutrient wealthy silt which helps crops grow might be affected.

5. Bio-Fuels – Bio-fuels are also a inexperienced energy source. They need been around for a very very long time however simply lately, people are starting to take notice.Throughout photosynthesis, plants grow and turn out biomass. Additionally referred to as bio matter, biomass can be used directly as fuel or to provide bio-fuels. Agriculturally produced biomass fuels, like bio-diesel, ethanol will be burned in internal combustion engines or boilers. Usually bio-fuel is burned to unleash its stored chemical energy. Liquid bio-fuel that is the one utilized in cars could be a natural and renewable domestic fuel which will solely be used for diesel engines. This may be created from vegetable oils largely soy and corn. After all diesel engines were originally created to run on vegetable oil! The great factor concerning bio-fuels is that they contains no petroleum, and they are nontoxic and biodegradable.

By fueling up with bio-fuel, you decrease the pollutants in the air as a result of it does not emit anything. Right currently, it is the sole fuel approved by the Environmental Protection Agency (EPA), passed each Heath-Effects Test of the Clean Air Act and meets the requirements of the California Air Resources Board (CARB).

Simply by reading through the offered alternative energy sources, you will be amazed at how nature works wonders. It is our responsibility to worry for the environment around us and keep it clean for generations before us.

No matter your beliefs, today we have a tendency to are now aware of the effects of worldwide warming. In the US, only seven% of green energy sources are used nationally. Fortunately, it isn’t too late and we have a tendency to will still amendment the result, which is why several are pushing for renewable energy sources to become additional prevalent in nowadays’s society. Find out how you can produce your own solar panels or wind generators and start using renewable energy.

The world is facing a crisis and is running out of ways to supply energy to supply sustenance to the growing demand for a lot of power. The intense energy crisis means we tend to should look out for renewable sources of energy rather than use energy sources like coal, oil and gas that will be exhausted by the top of the century.

Renewable energy resources like solar power, wind power and hydroelectricity are readily obtainable and there is no worry of ever exhausting these resources and they’re dependable as a result of they’re clean fuel alternatives. Fossil fuels not only pollute the environment by releasing huge amounts of carbon on burning, however will additionally be depleted, leaving mankind in a very rut. Here are a few various renewable resource solutions one can rely on for powering the future:

Solar energy –

The Sun, our powerful however natural nuclear powerhouse bathes the Earth with sunlight and warmth everyday. This energy resource will be easily tapped since it’s inexhaustible and is available in abundance, and is additionally free! With modern technological breakthroughs, daylight will now turn into electricity for domestic and business use.
It can be used at home to run nearly all household appliances and it makes your living a lot of greener indeed. You’ll be able to even attempt solar cooking, as a result of it’s said to be healthy living!

Solar energy is not solely green however additionally cost-efficient since it saves you plenty of money and little maintenance. Once installation, it can give you free power. Say goodbye to those electrical bills then!

Hydro Electricity –

Hydroelectricity, or in alternative words, producing electricity through water energy, is another such renewable energy resource. The Earth’s created up a lot of water than land, therefore, this is often a smart option. Dams help convert the water pressure and therefore the kinetic energy of water as it is pumped out of the reservoir into the turbines into electric current to assist power homes and the numerous electrical gadgets used at home. This supply of renewable energy’s the foremost widely used and accounts for additional than 90% of electrical power generated from renewable sources, worldwide.
However, some people feel that the only negative aspect of dams is that it can damage plants and animals life in the water.

Wind Energy –

Windmills are a typical sight against any Western landscape. These windmills were used to extract and pump water or to run mills or for towing boats. Once the 1800s because of industrialization, windmills began to be utilized in the assembly of electricity. Wind turbines will convert wind energy into electricity.
Wind energy’s a terribly promising prospective and will offer power, enough to run whole cities.

These days, thanks to varied analysis into renewable energy solutions, solar, wind and water energy will be easily harnessed to power our lives, hence creating it easier for us to wash up our planet and get rid of the pollution therefore that the subsequent generation can get pleasure from its beauty and reap the advantages of living in a greener world!

Renewable energy systems – Everything you wish to know

With the speedy decrease in the provision of standard energy sources such as people who come from fossil fuels, it has not been a marvel that a lot of and a lot of folks are making use of renewable energy systems so as to keep up with their needs. These are sorts of energy systems that are harnessed from nature. This suggests that they’re constantly replenished and has the chance of never ever running out. These characteristics have made them even additional desirable as compared to that of typical energy sources.

As is alleged earlier, renewable energy systems get their energy from nature. The foremost common of those natural sources embody the sun, water, wind, and geothermal. The current state of science and technology has even enabled man to harness energy from waste materials. This has led to a larger supply of energy that will be able to accommodate the growing wants of the globe in the years to come.

Of all the sources of renewable energy systems, water is considered to be one among the most commonly used kind of renewable energy source. This is often why it comes in varied kinds. There’s the hydroelectric energy that’s acquired from giant river dams. This can be usually found in giant river systems that have a high volume of water. This can be then used to supply kinetic energy, that is then used to produce electricity. Other sorts of water energy systems include people who utilize the energy of waves and people who create use of the energy of the tides.

Another common kind of renewable energy is that the one that’s derived from the sun. Solar energy, as it’s called has been in use since precedent days manner before complicated styles of technology has been invented and developed. Individuals have been using it to give light-weight and heat to their homes and to even cook their food. Now, it is being developed therefore that it will be in a position to provide electricity to a large range of homes. Varied strategies have been used to harness it effectively the most common of that is thru the utilization of a photovoltaic cell. This is often a kind of a cell that contains a special chemical that traps the sun’s energy so that it will be converted to electricity.

Aside from the primary 2, renewable energy can additionally be derived from the wind through the employment of wind farms. It uses the same principle found in hydroelectric dams to convert the wind energy to kinetic energy and then to electricity. Geothermal power is additionally a sensible form of renewable energy system. This, on the other hand, makes use of the warmth from deep inside the world to supply electricity. Various methods are used to do this like harnessing the steam that naturally comes out of fissures on the ground.

If developed even additional, renewable energy systems will simply supplement all the energy desires of the world these days and tomorrow. This can eliminate our dependence on fossil fuels, which has been providing as many harmful effects as its helpful benefits. Aside from that, it will facilitate in lowering the prices of providing power and energy to the world and even help in saving our environment.

Nuclear power plants work on the same principle as conventional power plants apart from the very fact that the warmth energy needed to convert the working medium into steam isn’t attained by burning fossil fuels but rather through the method of nuclear fission. During this reaction, a giant quantity of energy is released which the facility plant uses to supply electrical current.

Nuclear fission is attained by a nuclear reaction between serious atomic nuclei and neutrons, which are elementary particles while not electrical charge. During this nuclear reaction, the nuclei are softened into 2, releasing more neutrons within the process. These released neutrons then bombard into other atoms, resulting in additional fragmentation. This method is known as a nuclear fission chain reaction. A condition for this chain reaction to occur is when neutrons freed throughout fission react with different atomic nuclei to form more nuclear fission. This ensuing chain reaction continues until all out there material has been broken down. Nuclear fuel, typically a mix of various uranium isotopes, is cleaned during production and processed, usually into fuel rods.

The actual nuclear reaction takes place in microseconds, which will be demonstrated with the effect of an atom bomb. To be ready to use this kind of energy safely, it’s necessary for the chain reaction to not occur like an avalanche or like an explosion however rather that the release of energy and its use happen under full control so that the entire reaction can be maintained beneath control. This is often the kind of reaction which takes place in a nuclear reactor.

An atomic reactor is made of many enclosed systems which work together to get energy. The fission material, which is the fissionable isotope in the fuel rods, is placed where the nuclei get broken down. To initiate this reaction, the fuel rods can either be placed into or aloof from the reactor chamber. However, the output is controlled using rods made out of material, such as cadmium or metal containing boron, that can strongly absorb neutrons. The additional this regulating rod is pushed into the reactor, the additional the flow of neutrons are slowed. This regulation takes place rather automatically. In case of a danger of fallout, so-known as safety rods are dropped into the reactor that hamper the flow of neutrons to the point where the reaction stops outright.

The heat energy released during nuclear fission is drawn away by a working, highly radioactive medium inside the primary circuit (like water heated to a temperature of as high as 290°C below a high pressure in the order of 107 Pa or 100 bar, which is around 100 atmospheres) and diverted in the exchanger to the secondary circuit, where steam is generated which drives an electrical generator. A generator produces electrical energy that, with the help of a transformer, is converted into the required voltage and current values, in flip used for long distant transfer.

Substances suitable for slowing down fast moving neutrons are known as moderators (from the Latin word modero, that means that to moderate). Such substances contain, for example, hydrogen (paraffin) as a result of the hydrogen nucleus has practically the identical mass as a neutron. But, not only does normal water break down neutrons however it conjointly absorbs them. For that reason, a moderator tends to use heavy water (D2O) or graphite.

During nuclear fission, radioactive substances are created that radiate alpha, beta and gamma rays. These nuclear rays are terribly dangerous and could cause cancer (leukaemia) and alternative serious illnesses to humans. While alpha and beta rays will be successfully blocked using varied measures, gamma ray penetration can be a heavy problem. Gamma rays will be sufficiently blocked using barriers several meters thick created out of concrete, significant spar concrete or water. Nuclear radiation is additionally emitted from exhausted, fission material and radioactive substances will emit radiation over a amount of several voluminous years.

Another methodology how to come up with energy on nuclear principles is with thermonuclear fusion reactors. This nuclear process (synthesis) also creates energy within the sun. Using this nuclear fusion (thermonuclear reaction), the sun gains the required energy it wants to emit its radiation (nuclei synthesis). To a certain degree, nuclear fusion is the other of fission because it consists of a fusion of 2 lightweight atomic nuclei into a heavier atomic nucleus (or atomic nuclei), a process which, once again, releases energy. In technical apply, no kind of nuclear fusion has been successfully applied nonetheless, even in lightweight of decades of intensive research. To require advantage of nuclear fusion, a sufficient speed of atoms would wish to be attained under temperatures exceeding 100 million °C and the repulsive force of atoms would have to be overcome. An uncontrolled example of using nuclear fusion (nuclear synthesis, thermonuclear reaction) has been attained with hydrogen bombs.

Alternate energy is usually the name given to energy that is from another source other than the first fossil fuel like natural gas, coal and oil. Alternate energy is usually environmentally sound however sadly isn’t a common use, still the most popular use is renewable energies. Alternate energy sources will be wind, solar, biomass wave and tidal energy.

Another issue inflicting problems is population. Folks are using wood, minerals, contemporary water, food and energy each day. The increase in energy consumption is increasing pollution and having a large affect on the depletion of typical energy sources.

Currently we tend to rely heavily on fossil fuels and alternative non-renewable energy sources. This causes nice harm to our environment in the current, and if positive steps aren’t created to scale back this usage, can have an enormous have an effect on of future generations. Most of the present population depends on non-renewable energy.

When fossil fuels are burned they turn out carbon dioxide (CO2). When carbon dioxide is released into the atmosphere, it traps heat from the sun and prevents the warmth escaping from the Earths atmosphere into space. Carbon dioxide is a greenhouse gas, the amount of CO2 is increasing within the earths atmosphere,this is resulting in a general rise in temperature of the planet, we decision this global warming.

Renewable and alternate energy sources thus are a must. Renewable energy is attained from resources which can regenerate after consumption, and for these reasons unlike fossil fuels, renewable energy causes less green house gases.

Some countries are giving tax incentives and subsidies to the personal sector in order to encourage corporations to go green. Currently fourteen % of the worlds energy consumption is from renewable energy resources, however the potential for AER (alternate energy resources) could be ample enough to cover this several times over.

Many sources of AER are sunlight, wind, tidal, rain and geothermal heat. Wind energy comes from wind rotated turbines, this is a nice non-polluting energy source with low maintenance costs yearly, though the initial price to set it up is high. Solar energy comes from the sun. The suns rays will be collected and converted into heat and electricity,it can additionally be converted to thermal or heat energy(it can be used to heat water,also it can be used to heat homes and building and even greenhouses.

Biomass energy comes from wood,manure,waste from plants and several more. Biomass has numerous advantages and edges, the main one being it used materials that are sometimes thrown away or dumped. Fuels like ethanol are produced from biomass and can be easily used as an alternative to petrol.

Hydropower,water power or hydraulic power is energy that is collected from the movement of water.
There are many forms of water power currently in use or development. Some are purely mechanical however many primarily generate electricity. Broad categories embrace:

* Waterwheels, these are used for tons of years to power mills and machinery
* Hydroelectricity, sometimes bearing on hydroelectric dams, or run-of-the-river setups
* Damless hydro, these capture the kinetic energy in rivers, streams and oceans
* Vortex power, which creates vortices which will then be tapped for energy
* Tidal power, that captures energy from the tides in horizontal direction
* Tidal stream power, this will the identical however vertically
* Wave power, which uses the energy in waves
* Marine current power which captures the kinetic energy from marine currents.

These only show that to reduce the negative impact we are having on the world,we simply need to choose alternate methods of energy. If we do we tend to can see a bright and healthy future for our planet for our kids,and for our childrens children.

Water is one amongst the foremost common chemical compounds on earth, and the oceans offer seventy five% of the surface of the planet. It’s essential to life, and finding water on other planets is one in every of the main goals of science experiments performed by NASA. Water energy, through the utilization of waterwheels, was the first industrial process harnessed by personalities, used for powering lumber mills and cutting stone in ancient Egypt, water energy relies off of converting potential energy at the top of a well head to kinetic energy by the flow of water.

Water energy may be a renewable energy supply, and is primarily used to get electricity in the fashionable era through a method known as hydroelectric generation, where the flow of the water runs a turbine, that is used to drive a generator. The United States is one among the globe leaders in hydroelectric power generation, getting nearly ten% of its total power from hydroelectric plants; as the worth of oil increases, and volatility in the Middle East sends shocks through the energy markets, several more shoppers are seeing the benefit of water energy and hydro-electrical plants, even though dam construction projects are expensive, and significant environmental impacts.

Water energy in the shape of water wheels was 1st employed in classical times to run lumber mills and stone cutting saws; this needed coincidental placement of good water ways and the resource to be processed. Advances in gearing (most notably the slip cam and transverse axle) allowed water wheels to be used for standing “pestle type” grain mills starting in the second century BC, and these have been shown in movies set in the middle ages for years. The first Yank hydroelectric dam was opened in 1882; the primary hydroelectric dam was opened within the US, a marked departure from coal fired plants. As electrical power spread, the value of hydroelectric power increased, as electrical transmission permits the water energy to be transmitted to locales far from the water head of the dam.

Water energy is the results of changing potential energy from water stored “up hill” or at a better pressure level converted to kinetic energy; that conversion can be harnessed by water wheels or by electrical turbines. As a result of year in, year out rainfall patterns are fairly stable, hydroelectric power is predictable. It does not need burning fossil fuels; on the other hand, once the plant is made, increasing its output is sort of impossible, as the number of water energy is determined by the weight of water and the rate of flow or fall over the turbine.
