Solar Power- How Does It Save The Environment

Solar Power- How Does It Save The Environment

You’ve probably heard a lot about solar energy and how efficient it is. Moreover, over the last few years, there have been several moves to see how effectively we can use solar power in an attempt to alleviate the energy crisis that the world faces. So, how does using solar energy fit into the bigger picture of protecting our environment? The point is that even small changes in the way we do things go a long way in terms of saving our environment.

Solar energy is a renewable energy source
The sun offers us a great source of renewable energy; it’s been around for over four billion years and is likely to stay around for another five billion years, during its life it will supply us with a steady stream of energy. So, apart from the obvious fact of solar energy is in abundance, people who are environmentally conscious find that using solar energy is an excellent way to help protect the environment.
But what makes solar energy an attractive option is the fact that unlike polluting fossil fuels, its availability is not governed by the oil industry, an industry that is riddled with capitalistic individuals, and influenced heavily by several geographic and political factors that invariably affect the supply.
Solar Energy on the other hand is a clean environmentally friendly energy resource and a very viable alternative to existing fossil fuels that pollute our lands, water and air, threaten our health, and contribute substantially to global warming.

Solar energy transformed into thermal (or heat) energy can be used to:
* Cook food – Using Solar Cookers
* Heat water – in Houses, Office Buildings, or Swimming Pools.
* Heat closed spaces – a Greenhouse, a House or even other Buildings.

Solar energy can also be converted to electricity by using:
* Photovoltaic devices or “solar cells” that transforms sunlight into electricity. These systems are often used in areas with no regular electricity supply. Some common devices that are sometimes powered by these solar cells include, street lights, road signs and some gadgets like watches and even calculators.
* Solar Power Plants are electricity generating plants that use thermal energy obtained from the suns radiation to super heat liquids that in turn become steam and rotate the turbines of a generator to generate electricity.

How can solar power rescue the environment?
For starters, switching over to solar power would help cut back our dependence on organic fuels. This in itself is a huge saving, reduced hydrocarbons and emissions in the air, mean fresh cleaner air. Some ripple down effects would be, controlling the global warming, less acid rain, no smog the list can go on and on, however, let me elaborate some of the better know environmental benefits.
Decrease air pollution

The most commonly obvious benefit is the fact that by using solar energy we are able to reduce the levels of pollution. As we reduce the amount of fossil fuels being burnt and switch over instead to solar power from our needs there is a corresponding decrease in the amount of pollution produced. Solar electrification in some rural areas also decreases the dependence of the electricity grid and generators that run on petrol or diesel.

Offsets greenhouse gases
Solar Cell (PV systems) generates electricity with absolutely no carbon dioxide (CO2) emission. This in turn plays a significant step in reducing the overall greenhouse effect that we face. Apparently studies show that approximately six tons of carbon emissions are offset through the use of a single Solar cell over a period of twenty five years.
Conserve energy

The world over, and especially the third world countries have begun to embrace the conservation and use of solar electricity through several conservations programs to help conserve power for urban areas, city lighting as well as commercial and industrial needs. While solar plants and other forms of decentralised solar generated energy is used to serve the basic power consumption needs in the majority of the developing areas.

Reduces discarding dry cell batteries
People in several countries around the world rely heavily on the use of small dry-cell batteries for various gadgets, like flashlights and radio’s. These batteries are primarily composed of lead acid and sometimes other materials that can be toxic to us. When the battery is improperly disposed off, they start leaking; toxic chemical contents seep into the surroundings and contaminate the soil, water or air around it. By switching over to the use of solar energy the dependence on dry cells batteries reduces drastically and consequently all issues associated with its disposal.

Low cost energy alternative
Using solar energy at home substantially reduces the need for dependence on electricity or gas. Solar panels placed on your roof top collect the solar energy and store them away in batteries for later use. This power can be used to power up lights around the house in the evenings or when it is dark. Solar thermal converts can be used to heat water that or even your home again offering substantial savings on those fronts. Solar cooking ovens could be used during the day for baking and cooking meals.

The use of “Solar Energy”, a fresh, clean, free and abundant source of renewable energy will over the course of time reduce our dependence on other sources of energy that aren’t as helpful to our environment. If you want to make a difference to the world you live in, this is a wonderful place to start.

The Ins And Outs Of Diesel Generators

The Ins And Outs Of Diesel Generators

Generators are used for electric power generation. Two categories of diesel generators are basically available in market- one is portable generator and the other is standby generator. Diesel Generators are mostly used to make sure that electric appliances can be run when there is a power failure. Standby diesel generators are mostly used in homes and offices and installed outside the house or office building. These are plugged in home wiring or electric power circuit. These can automatically detect power failure and start supplying power with in moments. Portable diesel generators are used on sites where there is much less supply of electric power and they can only run few small appliances like refrigerators, televisions and turnaces.

Diesel generators use comparatively less fuel and thus are more fuel efficient than power generated by gasoline or natural gas. For every liter of fuel consumed, diesel generators can run 2 to 3 times more efficiently than natural gas engines. There is no need of frequent maintenance for diesel engines, but gasoline engines need more frequent maintenance. Most diesel engines designed with water-cooled engine up to a speed of 1800 rounds per minute. This makes sure that the engine is durable, and makes it most dependable of all generators.

Unlike other natural gas generators and gasoline generators, diesel engines are very safe to use because they work on direct injection principle and they do not have any spark plugs. The unavailability of spark plug keeps them safe from fire. Diesel generator has a better shelf life. This is the least flammable source of fuel, hence can be stored for more time.

The fuel for the diesel generators is available at all gas stations and can be collected in comfortable cans. Main problems in case of diesel generators are: it is very hard to start them in cold weather, they are noisy and emit more smoke. Home diesel generators may cost $ 800 for 4 kilowatt to $10000 for a 15-kilowatt depending upon the rating, voltage consumption, quality and brand name. Diesel generators can also be used in industrial purposes. For industrial purpose they are available in range of 500 kilowatt to 2000 kilowatt.

Fuels such as diesel, gasoline, natural gas, or propane can basically power home generators. Some models of diesel generators also designed with multi fuel capabilities. The fuel choice of will depend on availability of fuel during emergency times.
