Energy Efficiency and Renewable Energy Generation

Some of the best returns on investment are available through judicious application of energy efficiency strategies. We all know that adding foam-and-tape weather stripping around doors and windows costs little in cash and just a bit of time but can save hundreds of dollars a year in energy costs while improving comfort. Solar thermal or photovoltaic panels often provide an excellent return on investment as well as protection from rising electricity rates. Think big: whole-systems design can provide dramatic returns on investment by “tunneling through the cost barrier.” This involves designs that can end up reducing initial capital costs, such as using enough insulation and air sealing so that a smaller furnace suffices to heat a home.
