Answer 14

radioactivity, cancer and accident

Question 15

what are pros and cons of biomass

Answer 15

no net emissions of carbon dioxide ( if well manage ) but higher food price and food shortage and deforestation

Question 16

what are the pros and the cons of tide power

Answer 16

predicable and powerful, useful for protection barrages and no emissions but modify the hydrodynamic example sediment movement

Question 17

what are the pros and cons of geothermal

Answer 17

more site-specific. can be dangerous like earthquakes, emissions to soil and water, and solid waste

Question 18

    daylight for solar) what is also necessary for renewables to become a bigger part of our energy
    futures?

Answer 18

political actions

Question 19

14. Is an increase in efficiency likely to meet the increase in our energy that will most come in the
    future as economics continue to increase?

Answer 19

no we need to decrease the demand

Question 20
