I read a lot of warnings that we have gone past the point where the global warming would stop at 1.5 degrees C, so now we must stop emitting CO2 and also begin to remove it from the atmosphere. I read about carbon capture and storage but these have the major problem that the energy they need to do their job is causing more CO2 to be emitted. If you look at these systems as a whole, including the emissions from the power they use, then these systems look very inefficient. That is why so many advocate for reforestation to remove CO2.<\/p>\n
What is needed is to have all of the energy used in these CO2 capture systems to be from zero CO2 emitting sources such as wind, solar and hydropower. This means that we must put priority on converting our energy sources to be totally run from renewables: solar and wind. Furthermore, as we transition away from fossil fuels it will put a much greater demand on renewable electricity.<\/p>\n
The home heating that is done with natural gas will have to be switched to hydrogen or electric heat pumps. The water heaters will have to be heated by something other than natural gas — I’m thinking that a heat pump combined with solar water heating along with supplemental electric heating. Cooking would be with a microwave oven or electric range. Warm water for the bathroom could be solar heated water stored for later use. The kitchen hot water could be from a tankless electric water heater. The dishwasher is a huge electricity waster and should be eliminated.<\/p>\n
So now we have switched over to renewables. Much more electricity will be need to supply increased demand. The natural gas could be replaced by hydrogen, but this must be green (renewable) hydrogen that is not<\/em> made from fossil fuels. So this will take a large amount of electricity to electrolyze water into hydrogen. The hydrogen will be mostly used for heavy transportation.<\/p>\n","protected":false},"excerpt":{"rendered":" I read a lot of warnings that we have gone past the point where the global warming would stop at 1.5 degrees C, so now we must stop emitting CO2 and also begin to remove it from the atmosphere.
