If the Obama administration has its way, an additional $5 billion will be directed toward clean energy manufacturing.
Rows of solar panels lined up on a rooftop are the usual images consumers have of clean energy systems, or a group of wind turbines producing electricity from simple air flow. While these are accurate views of energy sources create energy, it leaves out one of the most cost-effective, and applicable of all clean energy systems ---namely solar heating tubes. This type of clean energy technology is used to provide hot water to homes and commercial buildings.
Simply outlined, a solar energy panel is a device that converts the sun's rays into electricity. It's also called 'photovoltaic' or PV cell, wherein photo stands for solar and voltaic means electricity. The electricity produced by these photovoltaic cells can be employed for energy usage in our day-to-day lives. These panels are often installed on rooftops. They are used both are a generator of electricity and a medium to heat water. Today, when power like coal and petrol are...
