Biofuels produced from biomass such as plants or organic waste could help to reduce both the world's dependence on oil and CO 2 production. These biofuels have the potential to cut CO 2 emission because the plants they are made from use CO 2 as they grow [6]. Biofuels and bioproducts produced from plant biomass would mitigate global warming.

Nuclear power debate - Wikipedia
Nuclear power debate - Wikipedia

The ,nuclear power debate, is a long-running controversy about the risks and benefits of using nuclear reactors to generate electricity for civilian purposes. The debate about nuclear power peaked during the 1970s and 1980s, as more and more reactors were built and came online, and "reached an intensity unprecedented in the history of technology controversies" in some countries.
