The Future of Solar Energy Technologies

Solar energy technologies has significantly advanced in this century.Many buildings are now incorporated with passive solar in their designs.The cost of using solar hot water systems is very close to conventional systems in some areas. And as the cost of solar    fresh water shortage    panel continues to decrease, these systems will be more widely used. The aim of solar industry in future is to provide half of the electricity of U.S. by 2025.

Germany and Japan have been leading in solar deployment for years.But the United States is catching up.Let us take California as an example.During 2000 and 2001,California experienced the rolling blackouts and soaring energy prices.This have motivated its leaders to diversify energy sources. In 2006,  California Solar Initiative was established, which dedicates $3.2 billion over 11 years to develop 3,000 megawatts of new solar electricity, equal to placing solar power systems on a million rooftops.

Other states in US are following California. Pennsylvania, New Jersey, Colorado and Arizona have specific requirements for solar energy as part of their renewable electricity standards. Many more states offer production incentives, rebates, tax incentives, loan and grant programs for solar industry. Even the federal government is offering a 30 percent tax credit (up to $2,000) for the purchase and installation of residential solar power systems and solar water heaters.
