Energy consumption
Scientists are trying to find more environmentally-friendly ways to generate electricity and a change in public opinion is pressuring governments to find better energy solutions for the planet. However, most of the electricity generated globally is still produced by Natural, finite fuel formed from the remains of living organisms, eg oil, coal and natural gas..
This is partly due to the fact that fossil fuels can generate a lot of power, compared to other energy sources, such as wind power or Energy generated from the movement of tides..
Other factors that could influence the decisions of governments to develop 'cleaner' energy are political and economic pressures. For example, countries whose economies are heavily based in extracting and exporting oil, have a strong interest in fossil fuels being used as a continuing energy source.
Other examples include growing economies. A large amount of energy is needed to support growing industries and to ensure they keep growing, which will allow them to compete with more developed countries.
