| Term | Definition |
|---|---|
| renewable resource | any material or energy source that cycles, or can be replaced easily within a short time period. |
| solar energy | radiant light and heat from the Sun that is harnessed using a range of ever-evolving technologies such as solar heating, photovoltaics, solar thermal energy, solar architecture, molten salt power plants and artificial photosynthesis. |
| biomass fuels | organic materials produced in a renewable manner. |
| geothermal energy | Geothermal energy is heat energy generated and stored in the Earth. |
| nonrenewable resources | material or energy source that cannot be replaced easily or requires extremely long amounts of time to replace itself. |
| fossil fuels | fuels such as natural gas, charcoal, peat, coal, and petroleum(oil) that release energy when burned |
| solar thermal system | uses the sun's energy, rather than fossil fuels, to generate low-cost, environmentally friendly thermal energy. |
| photovoltaic system | A photovoltaic system, also PV system or solar power system, is a power system designed to supply usable solar power by means of photovoltaics. |
| passive solar system | the thermal mass (concrete, masonry, or water) is located directly behind the south-facing glass and in front of the heated indoor space and so there is no direct heating |
| conservation | preservation, protection, or restoration of the natural environment, natural ecosystems, vegetation, and wildlife. |
| preservation | the state of being preserved, especially to a specified degree. |
