One of the most energy intensive and therefore costly processes in the average house is heating water. Learn more about how solar hot water systems can save you money and lessen your environmental impact.

Considering generating electricity via wind power? A vertical axis wind turbine may be more suitabled for your renewable energy needs than a traditional horizontal axis turbine - particularly in a suburban setting.

With carbon dioxide emissions snaring most of the media attention in relation to global warming, it's easy to forget that there's other greenhouse gases too - some with the potential to trap more heat and for longer than CO2. For example,  Nitrogen trifluoride (NF3), a gas used in the production of LCD and plasma screens has 17,000 times the GWP (global warming potential) of CO2. Here's a look at some of the substances, where they come from and what we can do to minimize emissions.

Wind turbines offer a partial solution to the world's green, renewable energy sourced electricity needs. This article is an overview of how wind turbines work and some of the issues surrounding their use.
