Geothermal Energy Part 2

Posted by Guest Editor on Thursday, December 27, 2012,

Geothermal energy can also be captured from heat pumps. Heat pumps tap into the heat near the Earth’s surface. This type of energy capturing can be used to heat water supplies or heat/cool buildings. Geothermal heat pumps transfer heat by pumping water or a refrigerant through pipes (also known as heat exchangers) below the Earth’s surface. During the winter months the water and refrigerants absorb heat from the Earth and deliver it to buildings and such. During summer months pumps are ...

How Methane Heating Works?

Posted by Guest Editor on Sunday, July 15, 2012, In : Must read

Natural gas derives from animal and plant matter that was heated and pressurized in earth’s layers (hence why it is referred to as “fossil fuel”). It is generally made up of methane, ethane, hexane, propane, heptanes, butane, and pentane; however, gas companies purify it until only methane is left. That way the gas used for heating burns cleanly. Methane is considered a clean fuel because compared to coal and oil, it is less chemically complex, releasing only carbon dioxide and water va...

What do you think of sustainable houses?
The technology used for building is improving every day, but if it's a super energy-efficient dwelling you're after, the tools are already well at hand. Once a year, the Northeast Sustainable Energy Association organizes a green buildings open house where energy nerds like us can see the latest in home efficiency.
