The Future of Solar Energy

Study is shedding new light on an unexpected source of power for heating houses and generating electricity-the sun.

The sun-directly or indirectly-is the primary source for many forms of power found on Earth. Solar power is clean, abundant and renewable.

Even though we think of solar energy as a brand new discovery, ancient civilizations found innovative approaches to utilize solar energy. Amongst them, the Greeks, Romans and Chinese all developed methods to utilize solar warmth for their homes, which includes working with southern exposures to maximize solar heating and creating use of solar lighting.

Now, thanks to innovative technologies, it's attainable to capture this energy, concentrate it, retailer it and convert it into electrical energy.

Sunlight is converted into electricity working with solar cells. Solar cells are also named photovoltaic cells, or "PV cells" for short. PV cells were first created within the 1950s for use in American space satellites. Nowadays, they may be employed for energy needs ranging from telecommunications to rural electrification. PV cells is usually identified on items we use every day, for instance calculators, flashlights, radios, landscape lighting and children's toys.

Portable solar photovoltaic units are also available for emergency and disaster use, like keeping cell phones and small appliances charged when the user is away from the grid or during blackouts.

Consumers can harness the power in the sun for themselves much more simply than ever. Solar panels you see on buildings and homes have been readily available in the marketplace for decades. New systems-which incorporate solar into roofing shingles-are now aesthetically pleasing, efficient and durable.

2006 ushers in new tax credits for solar energy technologies and buyers might also be eligible for state rebates.

Sunlight is not only employed to generate electricity. It's also utilized to heat water, which can be used to warm houses and businesses. Solar-powered radiant heating systems run some industrial processes and drive turbines to produce electrical energy. Lots of solar thermal technologies have been employed in homes for decades and may last more than 20 years.

Specialists believe that solar power technologies can benefit this nation in several strategies. They've the possible to assist diversify this country's power provide, decrease the dependence on imported fuels, boost air quality, offset greenhouse gas emissions and stimulate the economy by helping to make jobs in the manufacturing and installation of solar panel systems.
