Decarbonizing Electricity
摘要
The first step in replacing fossil fuels with carbon-neutral energy is to decarbonize electricity. Electric power does not create energy, but only transfers it. As such, replacing fossil fuels with carbon-neutral options as the primary power sources for electrical generation will be minimally disruptive to the economy and society. Electricity will flow as before, all appliances and devices will operate normally, and no one will know the difference except for those scientists measuring GHG levels in the atmosphere. If carbon-neutral or carbon-zero options are used to replace fossil fuels as the heat sources for thermoelectric power plants, existing electrical generating infrastructure can be retained, saving a substantial amount of both time and money. Options include biogas to replace natural gas and engineered geothermal or new nuclear technology to replace the heat from coal. The capital costs of engineered geothermal and new nuclear tech will be partly offset by lower operating expenses compared to coal or old style nuclear plants. Once the electric grid is fully decarbonized, it should be followed by decarbonization of the transportation sector and the industrial sector.
