Solar energy consists of the light and heat which is emitted by the sun as electromagnetic radiation. With today’s technology, we are able to capture this radiation and turn it into usable forms of solar energy – such as heating or electricity. Although one could go into technical dissertations on the subject of electromagnetic radiation, how it is converted into …

solar energy' alt='solar energy' /> Farooq Raza Qadri asked: “SOLAR ENERGY”   Today in Pakistan we are facing shortage of almost every basic need of life like water, gas, and especially electricity. It is the worst conditions we are facing now a days. The reason for that is…well we all know “THE REASONS” don’t we!!! Few days back I was …

Bryan Wong asked: In the early days of solar power there were huge installations necessary to make use of this energy source. The solar panels that were needed were larger than the average full grown man. This made the collection of solar power a bit of a challenge. Therefore making use of solar power was not suitable of everyone. It …

solar energy' alt='solar energy' /> nathan asked: Solar Power History “I have no doubt that we will be successful in harnessing the sun’s energy… If sunbeams were weapons of war, we would have had solar energy centuries ago.” These are words of Sir George Porter (December 1920 – August 2002), Nobel Laureate in Chemistry, which today is a reality. The …

You have probably heard it said by environmental groups that we should switch to solar energy as a power source because it is free, there is an unlimited supply, and it is a cleaner source of electrical power because there are no by-products (compared to fossil fuels like oil and gas which release greenhouse gases into the earth's atmosphere when burned for power.) However, can solar energy be a reliable and practical source of electrical power indeed?

Active solar builds on the same principles as passive solar but uses additional technology such as fans and pumps to maximize the desirable effects and minimize the undesirable ones. It is used to produce energy for heating and cooling spaces, to store [tag]energy[/tag] for later use, and to heat water. Most active [tag]solar energy[/tag] systems use specialized collectors to capture the rays and used the stored power and additional electricity as necessary to run pumps and fans for distribution.

Today, many Americans strive toward a clean, renewable energy source to meet the needs of the average consumer. That seems impractical, however, as fossil fuels and nuclear energy are excessively used in the country, causing environmental problems that pose a threat to living creatures. [tag]Solar power [/tag]has become a fortunate development in the modern world, as its advantages are far …

The world debates and frets over what to do about energy. Research goes on but in the end it will come down to consumers making choices that help set the course for the market place as to what gets built. Do we get electric cars again? Do houses get built with solar panels on them from the get go. What …
