Question

24 Match each renewable energy to the description that best fits.

Makes use of the earth's thermal gradient or internal heat to produce electricity or for a heating/cooling system. Provides greenhouse gas free electricity source using a spinning turbine. Potential impact to birds or wildlife needs to be considered when using. Makes use of organic matter (waste food, or crops) to burn as a fuel for heat, transportation, or electricity. Can reduce carbon output when plants are re-planted and they take carbon out of the atmosphere before they are burned. Produces some pollution when burned. Cellulosic sources are likely to replace corn based ethanol in the future.

Answer 1

Q.24. Answer-

renewable energy	description that best fits	Explanation
1. Wind	provides greenhouse gas free electricity source using a spinning turbine. Potential impact to birds or wildlife needs to be considered when using.	wind energy is used to harness electricity using turbines. Turbines are attached to generators which transport electricity into national grid. One of effect of wind turbine is that, many birds can be killed by blades, so that this criteria should be considered while setting wind turbine.
2. Geothermal	makes use of the Earth's thermal gradient or internal heat to produce electricity or for a heating/ cooling system	in geothermal energy, geothermal energy is harnessed from earth's heat present below surface.
3. Biomass	makes use of organic matter (waste food, or crops) to burn as a fuel for heat, transportation, or electricity. Can reduce carbon output when plants are re-planted and they take carbon out of the atmosphere before they are burned. Produces some pollution when burned. Cellulosic sources are likely to replace corn based ethanol in the future.	In this biomass (plant based) is converted into electricity. This waste from agriculture, domestic and industrial waste is converted into fuel in the form of solid, liquid and gaseous fuels.
