Document Summary
Lec 22 - bob howarth: a renewable energy future & Bridge fuel - continue to use fossil fuels, but continue to cut down on fossil fuels. Get same amount of energy from coal - producing more co2. Switch to natural gas from goal, less emissions. Conventional natural gas: methane gas that comes from places its formed originally (shale), and migrates to other places until it can"t migrate any more, it builds up. Put down pipe and gas flows to surface with its own pressure. High precision directional drilling: drill down until find shale formation, turn laterally, drill kilometers. Methane is potent gas, released at drilling sites. If we have any leaking, it gives large greenhouse gas footprint. It does leak all over the place, and we can"t see it with the naked eye - can be seen with infra-red cameras. Us is one of the primary causes of dramatic methane emissions recently, and a lot is from shale gas emissions.
