Document Summary

Can be replenish thru natural processes: 1) perpetual renewable resources. E. g. wind, sun: 2) potentially renewable resources: As long as natural processes are done. Fossil fuels, nuclear fuels, & metallic,non metallic minerals. Solar energy, chemical energy(photos), chemical energy(food), mechanical energy. 2 rules of thermodynamics: energy can be transformed, changing energy releases heat(by-product) When you"re convering energy, you lose heat. Top non-renewable resources : 1) oil, 2)coal(lignite, ____(sot one), ______(hard coal)) More industries are not using coals because of emissions: 3)natural gas(most abundant fossil fuel. Europe eurasia middle east): 4)nuclear energy- extremely powerful= main issue. Reserves are limited(even though 1lb gives a lot of energy) That can be buried or converted with energy. Two sources: 1)anything that grows e. g. plants, trees, 2) any waste from things that grows. Forest resources: 1)corniferous- soft tree, 2) decidious- hard tree, 3)________- found in tropical rainforest. Lots of o2, lots of animals take a lot of years to grow.
