Energy policy is the manner in which a given entity (often governmental) has decided to address issues of energy development including energy conversion, distribution and use as well as reduction of greenhouse gas emissions in order to contribute to climate change mitigation. The attributes of energy policy may include legislation, international treaties, incentives to investment, guidelines for energy conservation, taxation and other public policy techniques. Energy is a core component of modern economies. A functioning economy requires not only labor and capital but also energy, for manufacturing processes, transportation, communication, agriculture, and more. Energy planning is more detailed than energy policy. Energy policy is closely related to climate change policy because totalled worldwide the energy sector emits more greenhouse gas than other sectors. Access to energy is critical for basic social needs, such as lighting, heating, cooking, and healthcare. Given the importance of energy, the price of energy has a direct effect on jobs, economic productivity, business competitiveness, and the cost of goods and services. Frequently the dominant issue of energy policy is the risk of supply-demand mismatch (see: energy crisis). Current energy policies also address environmental issues (see: climate change), particularly challenging because of the need to reconcile global objectives and international rules with domestic needs and laws. The "human dimensions" of energy use are of increasing interest to business, utilities, and policymakers. Using the social sciences to gain insights into energy consumer behavior can help policymakers to make better decisions about broad-based climate and energy options. This could facilitate more efficient energy use, renewable-energy commercialization, and carbon-emission reductions.
