2) energy from a source that is not depleted when used, such as wind or solar power.
3) Essentially R-value is a measure of thermal resistance, or the ability to prevent the transfer of heat. The larger the number, the harder that insulation is working at preventing heat conduction. The less heat loss, the lower your energy bills. ... The standard R-value for roofs is R
4 Offshore wind power or offshore wind energy is the use of wind farms constructed in bodies of water, usually in the ocean, to harvest wind energy to generate electricity
5) machine for producing continuous power in which a wheel or rotor, typically fitted with vanes, is made to revolve by a fast-moving flow of water, steam, gas
6 large natural or artificial lake used as a source of water supply.
"the more water we use,
7) produced from hydropower. In 2015, hydropower generated 16.6% of the world's total electricity and 70% of all renewable electricity, and was

Generator- Electric generator, also called dynamo, any machine that converts mechanical energy to electricity for transmission and distribution over power lines to domestic, commercial, and industrial customers. Generators also produce the electrical power required for automobiles, aircraft, ships, and trains.
Renewable energy- The energy which can be collected from renewable resources, which are naturally replenished on a human timescale, such as sunlight, wind, rain, etc..
Energy efficiency- Energy efficiency simply means using less energy to perform the same task – that is, eliminating energy waste.
offshore wind farms-Offshore wind power or offshore wind energy is the use of wind farms constructed in bodies of water, usually in the ocean, to harvest wind energy to generate electricity.
Turbine-a rotary mechanical device that extracts energy from a fluid flow and converts it into useful work. The work produced by a turbine can be used for generating electrical power when combined with a generator.
Reservoir-a large lake where water is stored to be used by a particular area, city, etc.
Hydroelectric power- Hydroelectric energy, also called hydroelectric power or hydroelectricity, is a form of energy that harnesses the power of water in motion—such as water flowing over a waterfall—to generate electricity.
Fossil fuels-A fossil fuel is a fuel formed by natural processes, such as anaerobic decomposition of buried dead organisms, containing organic molecules originating in ancient photosynthesis that release energy in combustion.
