By 2035, nearly 40% of all new energy capacity will come from renewable energies according to a report from the National Conference of State Legislatures (NCSL). However, one resource or technology will not meet the energy needs of the future. It is necessary to develop a comprehensive plan that includes a combination of many technologies and resources. This plan may include energy efficiency, natural gas, cleaner coal technologies, nuclear energy, smart grid technologies and renewable energy. Local, state and federal governments will play an important role in shaping the future sources of energy, electricity transmission & delivery systems and electricity production & supply system.
