Solar Power and Wind Power

Let the Earth to breath. WE have to give little care to EARTH, WE have to reduce pollution.

There are other ways to produce power.

Solar power is another option. While we are making power using coal and other pollution making products we hurt Earth.

Solar and wind are the two better solutions for this. The nearby experiments proved that we can store heat, thereby make power later using this stored heat. This gives a great advantage to the solar power. During the night time and rainy seasons, we can use the stored heat.


"The sun may be about 148 million kilometers from Earth, but for many people, it is perhaps the most accessible power source when they think of 'green' energy. Solar power enjoyed a surge during the 1970's energy crisis, but where is it in the age of global warming? Increased attention on renewables has refocused the spot light on solar power, but today's solar is more than just photovoltaic cells on roof tops. "Mega Green Tech" explores the emerging world of Concentrated Solar Power (CSP), an evolving technology to harness the sun's rays on a massive scale to power entire communities. New CSP projects are thriving in hot spots like Nevada and Spain, where engineers race to tap this large-scale form of solar energy. But the technology is still dependent on one sometimes unpredictable factor: a sunny day. So a challenge remains -- to make solar more affordable and to somehow store its heat so this green energy can be relied upon whether rain or shine, day or night. We visit Nevada Solar One, a 400-acre solar field where hundreds of mirrors concentrate the sun's rays onto miles of high-tech tubing. A special oil that fills the tubes and is heated hot enough to generate steam-powered electricity, ultimately powering"-- National Geographic (Megastructures: Sun Engine)
