Decarbonization strategies
A comprehensive decarbonization plan describes how to generate enough green energy to replace coal, oil, and natural gas; and takes into consideration factors such as increasing GDP, increasing standard of living, and increasing efficiencies. Each year the world consumes 583 exajoules of heat energy. With 35 % efficient turbines, this yields 56000 TWh of electricity yearly. To decarbonize, that amount of electricity must be generated through means with very low CO2 emissions, such as hydroelectric dams, nuclear energy, wind farms and solar parks. If 56000 TWh were to be generated solely with the most powerful existing facility of each type of energy source, it would require:Decarbonisation activity by sector
Primary sector
Agriculture
Most of the agricultural facilities in the developed world are mechanized due to rural electrification.  Rural electrification has produced significant productivity gains, but it also uses a lot of energy.  For this and other reasons (such as transport costs) in a low-carbon society, rural areas would need available supplies of renewably produced electricity.Irrigation can be one of the main components of an agricultural facility's energy consumption.  In parts of California, it can be up to 90%.  In the low carbon economy, irrigation equipment will be maintained and continuously updated and farms will use less irrigation water.
Livestock operations can also use a lot of energy depending on how they are run.  Feedlots use animal feed made from corn, soybeans, and other crops.  Energy must be expended to produce these crops, process, and transport them.  Free-range animals find their own vegetation to feed on.  The farmer may expend energy to take care of that vegetation, but not nearly as much as the farmer growing cereal and oil-seed crops.
Many livestock operations currently use a lot of energy to water their livestock.  In the low-carbon economy, such operations will use more water conservation methods such as rainwater collection, water cisterns, etc., and they will also pump/distribute that water with on-site renewable energy sources (most likely wind and solar).
Due to rural electrification, most agricultural facilities in the developed world use a lot of electricity.  In a low-carbon economy, farms will be run and equipped to allow for greater energy efficiency.  Changes in the dairy industry include heat recovery, solar hearing, and use of biodigesters:Replacing livestock with plant-based alternatives is another way of reducing our carbon emissions. The carbon footprint of livestock is large - it provides just 18% of total calories but takes up 83% of farmland.Iceland
Iceland began utilising renewable energy early in the 20th century and so since has been a low-carbon economy. However, since dramatic economic growth, Iceland's emissions have increased significantly per capita. As of 2009, Iceland energy is sourced from mostly geothermal energy and hydropower, renewable energy in Iceland and, since 1999, has provided over 70% of the nation's primary energy and 99.9% of Iceland's electricity. As a result of this, Iceland's carbon emissions per capita are 62% lower than those of the United States despite using more primary energy per capita, due to the fact that it is renewable and low-cost. Iceland seeks carbon neutrality and expects to use 100% renewable energy by 2050 by generating hydrogen fuel from renewable energy sources.
