4. a process or technology for producing energy by harnessing the temperature differences between ocean surface waters and deep ocean waters
7. using solar energy to heat a fluid and then transfer the solar heat directly to the interior space
8. a cell producing an electric current directly from a chemical reaction
10. an area of land with a group of energy-producing windmills or wind turbines
12. an energy resource that is readily available or that can be replaced in a relatively short time
15. an energy harvesting technology, that converts solar energy into useful electricity
16. heat within the earth
17. the generation of electricity and other energy jointly, especially the utilization of the steam left over from electricity generation to produce heat

1. using less energy to get the same job done
2. a form of energy that harnesses the power of water in motion
3. any material derived from plants or animals
5. energy generated in ways that do not deplete natural resources or harm the environment
6. using the design of a building (versus technology) to collect, store, and distribute the suns energy
9. a form of power produced by the surge of ocean waters during the rises and fall of tides
11. a colorless volatile flammable liquid that is produced by natural fermentation of sugars
13. a colorless, odorless flammable gas is the main constituent of natural gas
