Solar Panels- They make electricity so you don’t have to buy it. You don’t have to use coal/oil/something else to create electricity, so it saves fossil fuels also.

Tankless Hot Water Heater- Heating water is the 2nd highest energy use in the home. This device saves energy by eliminating the storage tank for hot water that has to be constantly heated. You only heat the water you use.

Florescent Light Bulbs- These use less electricity than an incandescent bulb for the same amount of light.

Low-Flow Shower Heads- They save water, but still give the same amount of water pressure.

Deciduous Shade Trees- Trees provide shade during the warm months which reduce need for air conditioning. The leaves fall off in the winter, so they allow maximum solar radiation to reach house.

Thermal Massing- Thermal Mass is basically a thick layer of stone or concrete on the floor. They prevent large temperature fluctuations. Stone floors absorb and store heat during the day, and then they give off that heat at night, warming the house.

Salt Water Heat Exchange- Salt water in an enclosed system absorbs thermal energy during the day from the sun and passively releases heat into house at night warming it at night. The density of salt water allows it to retain heat and release the heat energy over a longer period of time than fresh water. These systems are typically installed on the south side of the house and can be placed behind a brick or stone wall, which in themselves absorb and emit heat.

Shades/Drapes- They allow you to reduce the heat energy entering the house during summer and maximize it during winter.

Geothermal Heat Pump- By burying coils in the ground and running them through a heat exchanger (heat pump) you’re combining the efficiency of a heat pump with a stable temperature. In the winter, heat from the Earth is carried into the house and in the summer heat from the house is absorbed by the Earth.

Cupola- This is a small dome on top of...
