Currently renewable energy only provides 8% of energy needs for the US. Many renewable energy technologies need to be developed further in order to make a greater contribution to the overall energy consumption of the US. While this process is underway, fossil fuels have to be used more efficiently and solar energy needs to be utilized since it is the most developed form of alternative energy.
