How does renewable energy help our future?

Posted by admin on April 21, 2012 in Renewable Energy with 7 Comments

Anything that can be used to make heat or electricity without unsustainable fuels and which does not make a net contribution of carbon dioxide to the atmosphere. This includes wind power, waves and the tides, solar energy, geothermal energy and biomass. Nuclear power, although it is low-carbon, cannot be counted as a renewable source of energy because its fuel, uranium, is finite.
How does all of that help our future? Thank you.

As the name suggest, it is renewable. it means that it can be used again and again but it will not last like coal and petroleum. for example, excess use of solar energy, wind energy will not reduce their stock and is always available forever.

    All the power sources you mention are unreliable especially solar and wind nuclear fission is a possibility but a better source of energy would be nuclear fusion their people working on it right now the only problem is getting the fusion reaction started once started there would be unlimited clean energy no waste once the fusion reaction stops their is no radio active waste you should look into it if we covered the entire U,S. with wind and solar we would only get about 2% of our power needs and that would be only during the day or when the wind blows.

    By conservation, we let nature as far as possible to run its course.

    Well by using renewable energy, we dont face the dreaded energy gap when our unrenewable fuels run out! But not just that, it helps the enviroment a great deal. Solar power provides a great source of renewable energy, and can even be harnessed on a cloudy day in England :D. However the amount of energy produced from a solar pannel can be sparse. Tidal power is great as its a good renewable source that rely’s on the sun and the moon, It is fairly powerful, however calm seas do not produce as much as stormy seas, therefore it may be hard to place all of these tidal power stations. Uranium, as well as being the best power source for the least amount of fuel, is very dangerous. To dispose of the radiation in the Uranium it must be buried under the ground, and to do that you run the risk of people digging it up and getting either severly hurt or death. Wind power is good, however the cost of the wind turbines is extremely high. Its all good though. So yeah it benefits the future, not sure if this is quite what your lookin for though đŸ˜€ ah well

    Nice Question,
    If you are interested to download this e-book see///greenproductsolutionpr.com///

    Solar Energy is the Future

    We consume fossil fuels at a greater rate than we have ever had over the past 50 years. That demand is fueled by the increase of cars on the street, the number of planes that take to the air and the number of homes that need electricity. Sadly, we will have depleted these resources by the end of this century which is why we have to come up with other ways to get power and solar energy may be the future.

    Solar energy is simply extracting the sun’s energy for power. Just to tell you how powerful the sun is, it can burn scrub lands and give you sunburn if you are out in the sun without any protection. In fact, the Greeks and the Chinese used this to set fire until the 1880’s by Charles Fritts made the first solar cell.

    Instead of using a heater to warm up the home, sunlight can be used to control the temperature. You will just need large windows and shades to control the amount of sunlight that will go inside and keep the heat absorbed during the day to remain at night.

    Solar energy can also provide warm water as it warms up cold water that passes down through the closed flat panels called collectors.

    But solar energy does not only give warmth to the home. It can also be used to help power it which reduces our dependence on non-renewable resources like oil or coal.

    This occurs when solar cells are installed on the roof so it will be able to capture as much solar rays as possible and then converts this into electricity. You will need 10 or 12 to capture at least a kilowatt of power and more if you are powering more than just your home.

    The only limitation which challenges the use of solar energy is that it can only generate power during the day. The answer to this is to put an auxiliary system in place that will store the energy and kick when the sun is not available. This comes in the form of batteries which will provide power in the evening or a brownout.

    Advances in technology have taken solar energy to the next level. NASA uses it to power satellites in orbit, solar panels installed onboard aircraft allow it to fly across oceans while cars can travel speeds up to 40 miles per hour. It is used to power a lighthouse so seafarers will be able to find their way at sea while aircraft can land in an airport in the middle of the frozen desert.

    Solar energy is safe for the environment since it does not emit any harmful gases or chemicals into the air. It is a renewable resource that has not yet been fully tapped by a lot of countries which makes it very viable for the future.

    But is it the only answer to reduce our dependence on oil? No because solar energy is just one of the options. We can also harness the power of the wind, the wave in the oceans, geothermal heat, hydroelectricity and a lot more instead of relying on coal or even nuclear energy that may harm the environment.

    It is something we have to push for the next generation.

    I hope this will helpful

    Solar finite =
    Silica is found in sand and quartz, and is commonly used to make glass and concrete. Each atom of silica, also called silicon dioxide, consists of one silicon atom and two oxygen atoms. To make the extremely pure silicon used for solar cells and computer chips, the silica must undergo several stages of processing to remove the oxygen and other impurities. Silicon is first extracted from silica and formed into thin wafers, which are then converted into semiconductors by doping them with other elements, such as boron and phosphorus. There are many other methods used to makes solar cells, and the latest thin-film cells can even be printed onto a flexible surface. However, the most common type is the silicon solar cell which is made using the floating zone technique and Czochralski process to purify and crystallize the silicon, before doping it with boron and phosphorus to make a semiconductor, and screen printing thin wires onto the front surface. Even after all this effort, the cells can only convert less than one fifth of the solar energy that reaches it.

    it can not only help us in fight against climate change and air pollution, but it can also improve our energy security and our energy independence because fossil fuels will eventually be depleted.
