Energy laws govern the use and taxation of energy, both renewable and non-renewable. These laws are the primary authorities related to energy. In contrast, energy policy refers to the policy and politics of energy.

Abandoned vehicles are decrepit cars or car wrecks or cars that have become useless in other ways, which are abandoned and illegally dumped in the environment. Abandoned vehicles will be tagged with an official notice when found or reported. Criteria for "abandonment" may differ, and a minimum duration of abandonment in the order of a few days to weeks is required. When reporting such a vehicle, the required data will usually comprise the exact location, the make, colour and type, and - if available and readable - possibly the VIN and the licence plate. Costs for removal will as a rule be taken by public councils.

To improve building energy efficiency, the Hong Kong Government formulated a Buildings Energy Efficiency Ordinance (建築物能源效益條例) which was passed by the Legislative Council in November 2010. Under the Ordinance, certain prescribed types of buildings have to comply with Building Energy Code (BEC) and/or Energy Audit Code (EAC). The Ordinance came into full operation on 21 September 2012.

Clean Tech Law contemplates a diverse set of legal and policy issues related to the development and commercialization of clean technology. These issues range from conventional natural resources law to cutting-edge intellectual property issues related to synthetic genomics and advanced materials. Clean tech law could also address issues and conflicts surrounding the placement of such technologies.

In the United States, a conservation easement is a power invested in a qualified private land conservation organization or government to constrain, as to a specified land area, the exercise of rights otherwise held by a landowner so as to achieve certain conservation purposes. It is an interest in real property established by agreement between a landowner and land trust or unit of government. The conservation easement "runs with the land", meaning it is applicable to both present and future owners of the land. The grant of conservation easement, as with any real property interest, is part of the chain of title for the property and is normally recorded in local land records.

The Energy Act 2004 is an Act of the Parliament of the United Kingdom.

The Energy Act 2010 is an Act of the Parliament of the United Kingdom pertaining to the regulation of energy usage and markets, with amendments to similar pieces of previous legislation. The Act was granted Royal Assent on 8 April 2010 along with a series of other bills during the wash-up period prior to the 2010 general election.

The Energy Act 2013 is an Act of the Parliament of the United Kingdom, relating to the energy sector. It succeeded the Energy Act 2010. The Act focuses on setting decarbonisation targets for the UK, and reforming the electricity market. The Act was intended by Secretary of State for Energy and Climate Change Ed Davey to "attract investment to bring about a once-in-a-generation transformation of our electricity market".

The Energy Efficiency and Conservation Act is an Act of Parliament in New Zealand. It is administered by the Ministry for the Environment.

The Energy Taxation Directive or ETD (2003/96/EC) is a European directive, which establishes the framework conditions of the European Union for the taxation of electricity, motor and aviation fuels and most heating fuels. The directive is part of European Union energy law; its core component is the setting of minimum tax rates for all Member States.

The United States Department of Defense is one of the largest single consumers of energy in the world, responsible for 93% of all US government fuel consumption in 2007 (Air Force: 52%; Navy: 33%; Army: 7%. Other DoD: 1%). In FY 2006, the DoD used almost 30,000 gigawatt hours (GWH) of electricity, at a cost of almost $2.2 billion. The DoD's electricity use would supply enough electricity to power more than 2.3 million average American homes. In electricity consumption, if it were a country, the DoD would rank 58th in the world, using slightly less than Denmark and slightly more than Syria (CIA World Factbook, 2006). The Department of Defense uses 4,600,000,000 US gallons (1.7×1010 L) of fuel annually, an average of 12,600,000 US gallons (48,000,000 L) of fuel per day. A large Army division may use about 6,000 US gallons (23,000 L) per day. According to the 2005 CIA World Factbook, if it were a country, the DoD would rank 34th in the world in average daily oil use, coming in just behind Iraq and just ahead of Sweden.

EurObserv'ER is a consortium dedicated to the monitoring of the development of the various sectors of renewable energies in the European Union.
The European Federation of Energy Traders (EFET) is an association of European energy traders in markets for wholesale electricity and gas. EFET was founded in 1999 in response to the liberalisation of electricity and gas markets within the European Union. EFET advocates policies and regulatory measures which allow electricity and gas trading to develop freely while encouraging good risk management practices and responsible corporate governance. In its role as a standard setting body, EFET aims to provide standard solutions to common aspects of wholesale energy transactions, such as contracting and data exchange.

The Renewable Energy Sources Act or EEG is a series of German laws that originally provided a feed-in tariff (FIT) scheme to encourage the generation of renewable electricity. The EEG 2014 specified the transition to an auction system for most technologies which has been finished with the current version EEG 2017.

Larry Persily is a newspaper publisher and former Federal Coordinator of the Alaska Natural Gas Transportation Projects 2010–2015. The office was charged with coordinating federal agency responses to private-sector efforts to develop a natural gas pipeline from Alaska's North Slope to supply the North American market. The Federal Coordinator is nominated with advice and consent of the Senate by the President of the United States. He was nominated by Barack Obama on December 9, 2009, and was confirmed by the United States Senate on March 10, 2010.

Philippines v. China, also known as the South China Sea Arbitration, was an arbitration case brought by the Republic of the Philippines against the People's Republic of China (PRC) under Annex VII to the United Nations Convention on the Law of the Sea concerning certain issues in the South China Sea, including the nine-dash line introduced by the Republic of China (Taiwan) since as early as 1947. A tribunal of arbitrators formed under the same annex appointed the Permanent Court of Arbitration (PCA) as the registry for the proceedings.

The Public Utility Holding Company Act of 1935 (PUHCA), also known as the Wheeler-Rayburn Act, was a US federal law giving the Securities and Exchange Commission authority to regulate, license, and break up electric utility holding companies. It limited holding company operations to a single state, thus subjecting them to effective state regulation. It also broke up any holding companies with more than two tiers, forcing divestitures so that each became a single integrated system serving a limited geographic area. Another purpose of the PUHCA was to keep utility holding companies engaged in regulated businesses from also engaging in unregulated businesses. The act was based on the conclusions and recommendations of the 1928-35 Federal Trade Commission investigation of the electric industry. On March 12, 1935, President Franklin D. Roosevelt released a report he commissioned by the National Power Policy Committee. This report became the template for the PUHCA. The political battle over its passage was one of the bitterest of the New Deal, and was followed by eleven years of legal appeals by holding companies led by the Electric Bond and Share Company, which finally completed its breakup in 1961.

Countries using or considering to use hydraulic fracturing have implemented different regulations, including developing federal and regional legislation, and local zoning limitations. In 2011, after public pressure France became the first nation to ban hydraulic fracturing, based on the precautionary principle as well as the principal of preventive and corrective action of environmental hazards. The ban was upheld by an October 2013 ruling of the Constitutional Council. Some other countries have placed a temporary moratorium on the practice. Countries like the United Kingdom and South Africa, have lifted their bans, choosing to focus on regulation instead of outright prohibition. Germany has announced draft regulations that would allow using hydraulic fracturing for the exploitation of shale gas deposits with the exception of wetland areas.
