- All of the below statements caution us about the dangers of continued over-reliance upon fossil fuels for future production, EXCEPT for this one. Please identify the statement that does NOT alert us that continued dependence solely upon fossil fuels for future productive activity may not be in the best interests of our global community. Group of answer choices Fossils Fuels have been associated with environmental damage, and some claim, possibly even global warming and climate change. Economies that possess oil, coal and other fossil fuels can control the price and availability of these and deny the use of these for political reasons. Better technology is enabling exploration and extraction of previously unknown or unavailable sources of oil, and even coal.How does generation of coal energy differ from that of nuclear energy?State two reasons why many countries are trying to reduce the amount of non renewable fuel they use?
- Indicate wether each of the following situations describes a transfer, une transformation of energy or both. a) The energy of the sun allows plants to perform photosynthesis. b) The energy real eased by a heating system makes it possible to warm the air in a house. c) Power plants produce electricity which then reaches our house. d) Food provides the energy we need to do our business daily.A Jeep gets about 15 miles per gallon during city driving and is estimated to emit 11.3 tons of CO2 per year. If a single tree can absorb 30 pounds of CO2 per year, how many trees would it take to absorb the jeep's emissions for one year? 1 ton equals 2000 pounds.A Honda Accord gets 24 miles per gallon in the city and is estimated to emit 7 tons of CO2 per year. How many trees would it take to absorb the Accord's emissions? Hint: 1 ton equals 2000 pounds and single tree can absorb 30 pounds of CO2 per year.
