摘要

Rhonda Saunders Fossil fuels are being rapidly depleted, especially easily accessed reserves of oil and gas. Further, fossil fuels account for most greenhouse gases emissions (GHG), including 74% of carbon dioxide, the most important GHG. Some scientists think that GHG atmospheric levels are already too high, and should be reduced.1 The only alternatives to fossil fuels, which presently account for over 80% of global primary energy, are nuclear energy and the various forms of renewable energy (RE). Nuclear energy today provides less that 6% of world energy, and official forecasts do not see its share rising much in coming decades,2 mainly because of its high costs and political problems. Other alternatives such as lowering atmospheric CO_2 emissions by carbon capture and storage from fossil fuel use, or capturing CO_2 directly from the atmosphere would either have limited global impact or entail heavy energy costs, if implemented at the needed scale. Like geoengineering, these approaches do not address fossil fuel depletion. Many researchers thus argue that RE will have to replace fossil fuels as the dominant global energy source in the coming decades.
