Sustainable and Renewable Energy

Many people are looking for alternative energy sources and sustainable ways of heating and cooling buildings both for economical and philosophical reasons.   Traditionally used fossil fuels like natural gas, propane and gasoline are becoming more difficult to extract, their price can fluctuate wildly, and the impacts of mistakes and miscalculations in their extraction can be widespread and disastrous.

Here are sustainable, renewable and alternative energy sources.  This section will be built up to incorporate more information on the following:

Passive Solar – A passive solar building is designed and built around the movement of the sun.  Because of how it is orientated and built, with southern facing windows, an overhang, is insulated and has thermal mass in the right places, it will be warm in the winter and cool in the summer if planned and built according to a few passive solar building rules.  It is called passive solar because the building simply, passively, sits where it is built.  Yes, it requires some planning, but is quite simple and efficient.  A building can have both active and passive solar elements to be optimally efficient.

Active Solar – The term “active solar” includes the action of pumps, fans and/or inverters that convert solar-based electricity from DC to AC. Because of the addition of electrically driven components, it is called “active solar” and can include any photovoltaic (PV) solar panel, thin-film PV, solar evacuated tubes for heating or anything else that converts, pumps, or motors anything.  See how active solar can be attached and work in a grid-tied house.

Geothermal – Geothermal energy utilizes the relatively stable temperature of the earth that is buried and stored a few feet under its surface. Geothermal energy can potentially be harnessed in the front or back yard of your home.

Hydro – ocean, river and gravitational

  1. For me,solar power is the best alternative source of energy. People can save a lot of money and will also aid the environment because it produces less carbon that is harmful to our environment.
