Document Summary
20% of people on earth consume 75% of energy. The u. s consumes in 1 year energy it took 1 million years to produce geologically. U. s oil has 25 more years: u. s coal has 3000 more years. China oil has 25 more years: china coal has 300 more years. Stabilization wedges: graphs with or without controls. All measures needed to slow anthropogenic contributions are here: video with smiths who produce 50 tons of co2 a year. Turn off lights, switch light bulbs, turn down thermostat, buy local food, unplug unused appliances, add insulation, recycle, use public transportation. 28 tons, 60% of emissions can be cut without a drastic change reduce reuse recycle. Led lights last for 50,000 hours despite costing the most. Oil, coal, natural gas, nuclear are non-renewable. Coal causes a ton of co2 and 2 cents per hour. Radioactive glass beads will not flow into groundwater: cannot be concentrated into weapons-grade material.
