Through Energy development, World energy supply and consumption and Jurisdiction

The energy sector emits more greenhouse gas worldwide than any other sector. Therefore, energy policies are closely related to climate policies. These decisions affect how high the greenhouse gas emissions by that country are.

The main components of energy policy include:

  • Legislation and regulation – Governments implement laws to promote renewable energy, set efficiency standards, and regulate fossil fuel extraction.
  • International treaties – Agreements like the Paris Climate Accord influence national energy strategies by setting emission reduction targets.
  • Subsidies and incentives – Many governments provide financial support for clean energy technologies while phasing out fossil fuel subsidies.
  • Public policy techniques – These include carbon pricing, renewable portfolio standards, and energy efficiency mandates.

The energy sector is the largest contributor to global greenhouse gas (GHG) emissions, accounting for over 73% of total CO2 emissions worldwide. As a result, energy policies are intrinsically linked to climate policies. Decisions regarding energy infrastructure—such as reliance on coal versus renewables—determine a nation's carbon footprint and its ability to meet international climate commitments (Intergovernmental Panel on Climate Change. For instance, countries investing in wind, solar, and nuclear energy typically achieve faster decarbonization than those dependent on coal and oil.

Given the urgency of climate change, many nations are transitioning toward low-carbon energy systems through policies like the U.S. Inflation Reduction Act (IRA) and the European Green Deal, which incentivize renewable energy adoption while reducing fossil fuel dependence.

Purposes

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.
