Renewable Energy – An Introduction

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.
