Learning About Photovoltaic Systems

Home photovoltaic systems convert light energy directly into electricity and offer consumers the ability to generate electricity in a clean, quiet, and reliable way.

Estimating PV System Size and Cost

Photovoltaic energy generating systems (PV systems) convert the sun's energy directly into electricity and can be off-grid or grid-connected. Both types of systems require specific components such as PV modules, inverter, and battery storage, and the final cost of the system depends on the sizing of the modules.

Energy Conservation in the Home

Lowering your household energy bill by saving energy in the areas of home heating and cooling can be accomplished by installing energy efficient appliances, sealing unwanted gaps and openings, installing high performance windows, and adding the right type of insulation for the space.

Passive Solar Design for Homes

Homes designed with passive solar principles use the changing position of the sun allowing a home to make the most use of the sun's heat in the winter, and at the same time, making sure the building will not get too hot in the summer.

Solar Water Heaters for Swimming Pools

Using the sun to heat a swimming pool can be an effective way to use solar energy. Solar pool heaters can be connected to the pool's existing water circulation system, need very little maintenance, and can extend your swimming season.

Environmental Pollutants from Electricity Production

Electricity generation produces more environmental pollutants than any other industry, and a better understanding of the environmental pollutants produced will allow consumers to make more informed decisions.

Wind Power Basics

Wind is created from differences between higher and lower pressure caused by unequal heating and cooling of the Earth and atmosphere. The greater the difference in pressure, the faster the wind speed, and the greater the power generation capability.

Grounded-Coupled Heat Pumps

While standard air source heat pumps are less effective in very cold climates and generally include electric heating elements for those times when they just can not handle the load, a ground-coupled heat pump addresses that issue.

Rural Renewable Applications

Whether the task was pumping water, drying crops or cooking, those who live off the land have always relied on three things: the sun, the wind, and the rain. Agricultural producers have long been on the forefront of renewable energy use.

Cooking With the Sun

Solar cookers can be used everyday or for solar picnics, they come in many types, and are easy to build or can be store bought. Above all, solar cooking works well, and is easy, fun and good for the environment.

Biomass: Nature’s Most Flexible Energy Resource

Biomass is plant material or animal waste that can be used as a fuel source. While wood is the best-known example of biomass, rice hulls, waste straw, manure, surplus corn, peanut shells and any other plentiful organic material can also be used.
