Types of energy investments There are many different types of energy investments. There are fossil fuels like petroleum and coal, renewable energy sources such as solar power and biofuels, nuclear energy, as well as companies that find ways to increase energy efficiency and conserve resources. There is a growing consensus among citizens, politicians and energy experts that the United States must reduce its dependence on foreign petroleum as it faces increasing energy demands. An increasing recognition of dwindling petroleum reserves, political instability in major petroleum producing countries, and concerns about global warming have made current and future energy use a major focus of foreign and domestic policy discussions. It has also brought new interest and attention to energy investments that are an alternative to fossil fuels. Building new nuclear power plants is under discussion, although this remains controversial, and the economic stimulus plan of the Obama administration includes funding for research and development of alternative energy sources such as solar and wind power, and biofuels.
