Document Summary
Carbon cycle takes millions of years to turn and burning fossil fuels short circuits and brings long buried carbons into atmosphere. Energy from a source that is not depleted by energy extraction or is quickly replenished: solar energy, tidal and wave power, wind power can be on or off shore, hydroelectric power, geothermal energy material from. Earth"s interior and decay of radioactive isotopes: raw biomass and biofuel ex. Reliable, predictable and never runs out , tide has slowed down earth"s rotation. Effect on marine life- turbines kill, acoustic issues, high cost. Numerous- flexible, cost is low, useful for flood control. Generates a lot of greenhouse gases, environmental damage, displacement of people: low energy density wind or solar has to be dispersed, can be too expensive to elicit much market interest. ** externalities = cost or benefit from an economic transaction to parties not involved in the transaction. Plants use light and convert it to chemical energy.
