Go Greener Tips

There can be growing concern over environmental degradation triggered by standard sources of energy. Due to these factors different sources of energy have gained lots of prominence in the recent past. Government help and emphasis on clear sources of vitality have additionally resulted in new capacities being constructed on the premise of such sources. To additional incentivize and improve investment in this sector, the federal government recently began allowing power vegetation to earn a higher in excess of 16% to 17% for power produced from different sources of energy. Benefits of Solar Photovoltaic are it operates on the freely obtainable solar power thus saving the expenditure on electricity and fossil fuels, no fear of power cuts, it is trouble free, pollution free, and noise free, has a long life and is reliable, simple to handle and operate, and negligible value of operation and maintenance. Among the non-conventional sources of energy, solar vitality is most readily available and is present in abundance. Unlike wind energy, solar vitality has not yet been explored in India. It at present has a solar-based energy generation capacity of about 200 mw.

There is also emphasis on building about 20000 mw of solar capability by 2020. There are few listed players offering the expertise (photovoltaic energy systems, etc) required for producing power from solar energy. Companies like Webel SL Energy, Moser Baer and XL Telecom are the known listed companies. Others like Euro Multivision not too long ago came out with an IPO. Webel has increased its generation capacity to about a hundred mw at present from forty two mw in FY08. However, it nonetheless generates a large part of its revenue from international markets.

Nearly fifty five per cent of the State’s population depends on agriculture for its livelihood. This sector has been the single largest provider of employment to the rural people of the State. However, the contribution of agriculture sector within the State economic system is lowering over the period because of unfavorable agro-climatic scenario and sooner growth in other sectors particularly in providers sector. Nearly, one-third area of the State falls beneath rain-shadow region, where the rains are scanty and erratic. In these areas, only dry land cultivation is undertaken. Out of the overall geographical area of the state, the proportion of area below agriculture (56.8 per cent in 2005-06) is rather more than that at national degree (43.2 percent). Despite big spending on the irrigation projects, the proportion of gross space irrigated to gross cropped area within the state is around 17 p.c as against about forty three per cent at the national level. Most of the electricity in Maharashtra state comes from fossil-fuels like coal, oil and natural gas.

Today the demand of electricity in Maharashtra state is increasing where because the reserves of the fossil-fuel are depleting every day. The demand of electrical energy is already greater than the manufacturing of electricity. We can really feel this fact from the electricity-cuts during summer. Luckily Sun throws large amount of energy over Maharashtra state, that if we will trap jiffy of solar power then it is possible to supply electricity for complete year to India. Most components of India get 7 KWH/ sq-meter of power per day averaged over a year. The use of photovoltaic (PV) energy to run irrigation methods was inspired several years ago by various governments and international agencies, but this was less successful than expected, partly because of high costs. As solar home systems have gotten more established and there is increasing native technical support for PV technology, the usage of PV for irrigation is rising as well. Solar power systems collect energy from sunlight; thermal programs convert it to heat, while PV methods convert it to electricity. The quantity of power produced varies in accordance with the system’s location, the time of yr and the weather, though some energy is produced even on cloudy days.

Average isolation showing land area (small black dots) required to replace the world primary energy supply with photo voltaic electricity. Isolation for most people is from one hundred fifty to 300 W/m² or 3.5 to 7.0 kWh/m²/day. Solar power refers primary to the usage of solar radiation for sensible ends. However, all renewable energies, apart from geothermal and tidal, derive their vitality from the sun. The benefits of off-grid solar PV in creating countries embody the avoidance of fire risk and pollution from kerosene lamps, the flexibility to charge mobile phones, and the provision of radio, tv and computer services.

HISTORY OF SOLAR SYSTEM

The existence of the photovoltaic effect was shown by physicist Becquerel in 1839. By 1870, Professor W. Grylls Adams experimented on the effect of light on selenium, verifying that a circulate of electrical energy was created, that was called “photoelectric”. By 1885, Charles Fritts built the primary photoelectric module, showing evidence of the direct conversion of sunlight energy into electric energy. In 1921 Albert Einstein gained the Nobel Prize for explanatory theories on photovoltaic effect. In 1953, executives from Bell offered the so-called Solar Battery Bell, exhibiting a panel of photovoltaic cells that powered a miniature Ferris wheel. Within a couple of years, selenium was replaced by silicon as the essential material for the cells.

AGRICULTURAL APPLICATIONS OF SOLAR ENERGY IN MAHARASHTRA

Among the renewable sources of energy, solar vitality has an enormous potential for energy generation in Maharashtra. There are 250-300 days of clear solar with an obtainable average radiation of 4 to six kWh/m²over a day. There is a capacity to generate 1.5 million units/MW/year by way of solar photovoltaic programs & up to 2.5 million units/MW/ year via solar thermal systemsaharatra is already in process to spice up this enormous source and solar venture developers can submit their proposals to MEDA. Solar vitality can supply and/or supplement many farm vitality requirements. The following is a brief discussion of some applications of solar vitality technologies in agriculture. For more information, you may want to consult the publications listed below. Depending on location, a 1 kW system can produce from 1,400 kWh to 2,000 kWh per year. Watts are units of power measured over one second. If one watt of electrical power is used per hour, the full volume of power consumed is expressed as one watt hour, or 1Wh. Similarly, 1,000 watts of power is expressed as one kilowatt (1kW) and 1,000 watt hours as one kilowatt hour (1kWh). If a 2kW system produces power continuously for five hours, the entire volume of power generated is expressed as 10kWh.

CROP AND GRAIN DRYING

As solar through great amount of power in Maharashtra state, utilizing the solar to dry crops and grain is among the oldest and most generally used purposes of photo voltaic energy. The simplest and least expensive technique is to allow crops to dry naturally within the field, or to unfold grain and fruit out within the sun after harvesting. The disadvantage of those methods is that the crops and grain are subject to damage by birds, rodents, wind, and rain, and contamination by windblown mud and dirt. More refined solar dryers shield grain and fruit, cut back losses, dry faster and extra uniformly, and produce a better quality product than open-air methods.

The basic components of a solar dryer are an enclosure or shed, screened drying trays or racks, and a solar collector. In hot, arid climates the collector could not even be necessary. The southern aspect of the enclosure itself could be glazed to permit sunlight to dry the material. The collector can be as simple as a glazed field with a dark coloured interior to soak up the solar energy that heats air. The air heated in the solar collector moves, both by natural convection or pressured by a fan, up through the fabric being dried. The dimension of the collector and charge of airflow depends on the amount of fabric being dried, the moisture content of the material, the humidity within the air, and the average amount of photo voltaic radiation available through the drying season.

SPACE AND WATER HEATING

Livestock and dairy operations typically have substantial air and water heating requirements. Modern pig and poultry farms increase animals in enclosed buildings, where it is necessary to carefully management temperature and air quality to maximise the health and development of the animals. These facilities need to switch the indoor air recurrently to remove moisture, poisonous gases, odors, and dust. Heating this air, when necessary, requires massive amounts of energy. With correct planning and design, solar air/space heaters could be incorporated into farm buildings to preheat incoming recent air. These systems may induce or enhance natural ventilation levels during summer months. Solar water heating techniques can present low to medium temperature hot water for pen cleaning. Commercial dairy farms use large amounts of power to warmth water to scrub equipment, in addition to to warm and stimulate cows’ udders. Heating water and cooling milk can account for as much as 40% of the vitality used on a dairy farm. Solar water heating systems could also be used to provide all or part of these sizzling water requirements.

GREENHOUSE HEATING

Another agricultural utility of solar vitality is greenhouse heating. Commercial greenhouses typically depend on the sun to produce their lighting needs, but usually are not designed to use the solar for heating. They depend on gas or oil heaters to take care of the temperatures necessary to grow plants in the colder months. Solar greenhouses, however, are designed to utilize solar power for both heating and lighting. A solar greenhouse has thermal mass to collect and store solar warmth energy, and insulation to retain this warmth for use throughout the night and on cloudy days. A solar greenhouse is oriented to maximise southern glazing exposure. Its northern facet has little or no glazing, and is effectively insulated. To reduce heat loss, the glazing itself is also more efficient than single-pane glass, and various products are available ranging from double pane to “cellular” glazing. A solar greenhouse reduces the necessity for fossil fuels for heating. A fuel or oil heater may function a back-up heater, or to extend carbon dioxide levels to induce higher plant growth.

REMOTE ELECTRICITY SUPPLY

Solar electric, or photovoltaic (PV), methods convert sunlight directly to electricity. They can power an electrical appliance directly, or retailer solar power in a battery. A “remote” location could be several miles or as little as 50 ft (15 meters) from a power source. PV systems could be less expensive than putting in power traces and step down transformers in applications comparable to electrical fencing, lighting, and water pumping.

WATER PUMPING

Photovoltaic (PV) water pumping systems stands out as the most cost-effective water pumping choice in areas where there is no such thing as a existing power line. When properly sized and installed, PV water pumps are very reliable and require little maintenance. The size and value of a PV water pumping system is determined by the local solar resource, the pumping depth, water demand, and system buy and set up costs. Although today’s prices for PV panels make most crop irrigation programs too expensive, PV techniques are very cost effective for distant livestock water supply, pond aeration, and small irrigation systems.

Government Policy of Village power

First goal of this is to present energy for cooking, electricity and motive power by various forms of locally out there biomass materials with vitality production & distribution to be managed by local communities. Second goal is to envisage energy plan which includes assessment of whole demand, resource availability and an appropriate technology mix to fulfill demand.

Village Energy Security Programme was launched by Ministry of Non-conventional Energy Sources (MNES), New Delhi of Govt. of India in the year 2004-05. The programme is deliberate in such a fashion that it ought to facilitate households of these remote villages / hamlets which still don’t have excess to standard energy sources and won’t be electrified by standard sources till 2012. It has immense social aspect in development of nation as it’ll provide total vitality security (Electricity, Cooking, Motive Power etc) to the villagers to make them self-sufficient.Under village energy security programme (VESP) the train of identification of these un-electrified villages which aren’t feasible to be connected by means of the grid are thought-about as ‘remote’ villages. A detailed survey of the distant villages is to be undertaken conserving in view the feasibility and viability of options for biomass gasification / biofuel base power generation, improved chullha / biogas crops for cooking vitality etc. In common villages between minimal 25 households and most 200 households might be considered as potential village beneath VESP. The major and the foremost goal of this programme is the concrete participation of villagers that to in-particular women’s participation by the formation of Village Energy Committee (VEC). The Programme envisages some contribution towards total project price from respective state governments / beneficiary.

CENTRAL GOVERNMENT POLICY

Village Energy Security Programme (VESP) is the programmers launched by Ministry of Non-conventional Energy Sources (MNES), New Delhi keeping in view to make a specific census village or a hamlet of census village self sustaining from the viewpoint of Energy necessities using locally available renewable energy sources & full participation of local community.

SOME SUGGESTIONS
Agricultural technology is changing rapidly. Farm machinery, farm buildings, and production facilities are consistently being improved. You ought to consider these elements when buying and putting in a solar system. Payback periods may be shortened by the multiple use of a photo voltaic system, akin to for house heating and crop drying.

Solar energy is a superb alternative energy supply because there isn’t any pollution generated while it is being used so we actually reduce pollution with each watt of energy generated from the sun. Even if we can’t cut back how much vitality is used we should no less than control the place that power comes from.

There is no cost involved with using solar energy other that the cost of manufacturing the components, purchasing and installation. After your preliminary investment there isn’t a further cost related to its use.

Solar power systems are versatile and expandable. This means that your first solar project is usually a small one and you may expand your solar electrical system to meet your wants by putting in more panels. By beginning with a small project you’ll be able to avoid a serious investment up front.

As our use of solar power increases, our demand on fossil fuels decreases. This will prolong the time before our provide of fossil fuels (oil and pure gas etc…) expires or costs change into so high only the rich can afford them.

There is no pollution associated with the usage of solar power. No smoke stacks pumping greenhouse gasses into the air means much less pollution.

A solar electric system installed in a house could potentially eliminate 18 tons of greenhouse fuel emissions from the surroundings each year.

Using solar energy is a silent process. No noise pollution.

With area heating home equipment using fossil fuels there is at all times the threat of a cracked warmth exchanger, which might cause CO2 poisoning (Carbon Dioxide). This will not be a downside when using solar energy.
A great advantage of photo voltaic is for remote applications. It is one of the simplest ways to provide electricity to remoted places on the earth where the cost associated with installing power distribution traces makes it impractical or impossible.

Solar energy can be used to heat water and for space heating.

You can build your personal system from collecting the components required or purchase one of many many photo voltaic kits which are available. Using kits takes a whole lot of the work out of building your individual system.

Renewable energy indeed is effective and has helped thousands of household nowadays in cutting their electricity bill. It is not necessary that we will be enslaved by electricity suppliers with their expensive electricity. We can always study basic solar energy facts and renewable energy information on http://www.freealternativeenergyresources.com/ and learn how to save and use electricity wisely.
