Solar Thermal System: Benefits Vs Problems?
Solar thermal systems are the latest green renewable technology that derives energy from the sun to produce heat. This heat is then transferred to warm water for utilization or regulates temperatures within households, offices and even industries. Varying qualities of equipment results in variation of performance in terms of efficiency and quantity of energy being wasted depending upon quality. ...

Harnessing the Sun`s Energy for Water and Space Heating
The pace of solar energy development is accelerating as the installation of rooftop solar water heaters takes off. Unlike solar photovoltaic (PV) panels that convert solar radiation into electricity, these "solar thermal collectors" use the sun's energy to heat water, space, or both. China had an estimated 168 million square meters (1.8 billion square feet) of rooftop solar thermal collectors ...

How efficiency makes solar affordable
By Reid Smith October 27, 2010 When solar energy companies think about how to reduce the cost of their product, typically a lot of time and money goes toward increasing the efficiency of solar panels and their manufacturing process. Reducing the production cost decreases the final cost the consumer will have to pay. However, few solar companies start by making the building more ...

No place like home for energy savings
Apparently there is no place like home, even when it comes to fulfilling lofty wishes like fixing our energy supply. A recent White House task force on the middle class finds that our homes generate more than 20% of the nation's carbon dioxide emissions. If we make our houses more efficient, we can significantly cut emissions and reduce energy use by 40%, a move that could lower our bills by $21 ...
