The Future Of Solar Energy
Investigation 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 major source for most types of power found on Earth. Solar power is clean, abundant and renewable.
Although we think of solar energy as a new discovery, ancient civilizations found innovative ways to use solar power. Among them, the Greeks, Romans and Chinese all developed ways to use solar warmth for their houses, such as using southern exposures to maximize solar heating and creating use of solar lighting.
Now, thanks to innovative technologies, it really is doable to capture this power, concentrate it, shop it and convert it into electricity.
Sunlight is converted into electricity using solar cells. Solar cells are also called photovoltaic cells, or “PV cells” for short. PV cells were first developed inside the 1950s for use in American space satellites. At this time, they may be employed for energy needs ranging from telecommunications to rural electrification. PV cells is usually found on items we use daily, such as calculators, flashlights, radios, landscape lighting and children’s toys.
Portable solar photovoltaic units are also available for emergency and disaster use, just like keeping cell phones and tiny appliances charged when the user is away from the grid or for the duration of blackouts.
Buyers can harness the energy in the sun for themselves more simply than ever. Solar panels you see on buildings and houses have been obtainable available on the market for decades. New systems-which incorporate solar into roofing shingles-are now aesthetically pleasing, effective and durable.
2006 ushers in new tax credits for solar power technologies and buyers might also be eligible for state rebates.
Sunlight is not only employed to generate electricity. It’s also used to heat water, which is usually employed to warm houses and companies. Solar-powered radiant heating systems run some industrial processes and drive turbines to generate electricity. Lots of solar thermal technologies have been employed in houses for decades and can last more than 20 years.
Authorities think that solar power technologies can benefit this nation in lots of ways. They have the possible to assist diversify this country’s power provide, reduce the dependence on imported fuels, enhance air quality, offset greenhouse gas emissions and stimulate the economy by helping to make jobs inside the manufacturing and installation of solar power systems.
