Energy development is a field of endeavor focused on making available sufficient primary energy sources and secondary energy forms to meet the needs of society.
These endeavors encompass those which provide for the production of conventional, alternative and renewable sources of energy, and for the recovery and reuse of energy that would otherwise be wasted.
Energy conservation and efficiency measures reduce the impact of energy development, and can have benefits to society with changes in economic cost and with changes in the environmental effects.
Contemporary industrial societies use primary and secondary energy sources for transportation and the production of many manufactured goods.
Also, large industrial populations have various generation and delivery services for energy distribution and end-user utilization.
This energy is used by people who can afford the cost to live under various climatic conditions through the use of heating, ventilation, and/or air conditioning.
Level of use of external energy sources differs across societies, along with the convenience, levels of traffic congestion, pollution sources and availability of domestic energy sources.
Thousands of people in society are employed in the energy industry, of which subjectively influence and impact behaviors.
The conventional industry comprises the petroleum industry the gas industry the electrical power industry the coal industry, and the nuclear power industry.
New energy industries include the renewable energy industry, comprising alternative and sustainable manufacture, distribution, and sale of alternative fuels.
While there is the development of new hydrocarbon sources, including deepwater/horizontal drilling and fracking, are contentiously underway, commitments to mitigate climate change are driving efforts to develop sources of alternative and renewable energy.
