Energy conservation is the effort made to reduce the consumption of energy by using less of an energy service. This can be achieved either by using energy more efficiently or by reducing the amount of service used. Energy conservation is a part of the concept of Eco-sufficiency. Energy conservation measures (ECMs) in buildings reduce the need for energy services and can result in increased environmental quality, national security, personal financial security and higher savings. It is at the top of the sustainable energy hierarchy. It also lowers energy costs by preventing future resource depletion.
Photovoltaics (PV) is the conversion of light into electricity using semiconducting materials that exhibit the photovoltaic effect, a phenomenon studied in physics, photochemistry, and electrochemistry. The photovoltaic effect is commercially utilized for electricity generation and as photosensors.
The United Kingdom's Climate Change Programme was launched in November 2000 by the British government in response to its commitment agreed at the 1992 United Nations Conference on Environment and Development (UNCED). The 2000 programme was updated in March 2006 following a review launched in September 2004.
ActewAGL is an Australian multi-utility joint venture company that provides utility services in the Australian Capital Territory (ACT) and south-east New South Wales. The company was formed in October 2000 between the Australian Gas Light Company and ACTEW Corporation, an ACT Government-owned corporation.
The Global Warming Solutions Act of 2006, or Assembly Bill (AB) 32, is a California State Law that fights global warming by establishing a comprehensive program to reduce greenhouse gas emissions from all sources throughout the state. AB32 was co-authored by then-Assemblymember Fran Pavley and then-Speaker of the California Assembly Fabian Nunez and signed into law by Governor Arnold Schwarzenegger on September 27, 2006.
The Global Warming Pollution Reduction Act of 2007 (S. 309) was a bill proposed to amend the 1963 Clean Air Act, a bill that aimed to reduce emissions of carbon dioxide (CO2). A U.S. Senator, Bernie Sanders (I-VT), introduced the resolution in the 110th United States Congress on January 16, 2007. The bill was referred to the Senate Committee on Environment and Public Works but was not enacted into law.
A feed-in tariff is a policy mechanism designed to accelerate investment in renewable energy technologies by offering long-term contracts to renewable energy producers. Their goal is to offer cost-based compensation to renewable energy producers, providing price certainty and long-term contracts that help finance renewable energy investments. Typically, FITs award different prices to different sources of renewable energy in order to encourage development of one technology over another. For example, technologies such as wind power and solar PV, are awarded a higher price perkWh than tidal power. FITs often include a "degression", a gradual decrease of the price or tariff, in order to follow and encourage technological cost reductions.
The California Energy Code is the sixth section of the California Building Standards Code. The code was created by the California Building Standards Commission in 1978 in response to a legislative mandate to reduce California's energy consumption. These standards are updated periodically by the California Energy Commission. The code includes energy conservation standards applicable to most buildings throughout California.
Solar power in the United States includes utility-scale solar power plants as well as local distributed generation, mostly from rooftop photovoltaics. As of the end of 2020, the United States had 97,275 megawatts (MW) of installed photovoltaic and concentrated solar power capacity combined. In 2018, utility scale solar power generated 66.6 terawatt-hours (TWh), 1.66% of total U.S. electricity. During the same time period total solar generation, including estimated small scale photovoltaic generation, was 96.1 TWh, 2.30% of total U.S. electricity. In terms of total cumulative installed capacity, by year end 2017 the United States ranked 2nd in the world behind China. In 2016, 39% of all new electricity generation capacity in the country came from solar, more than any other source and ahead of natural gas (29%). By 2015, solar employment had overtaken oil and gas as well as coal employment in the United States. In 2016, more than 260,000 Americans were employed in the solar industry.
New Energy for America was a plan led by Barack Obama and Joe Biden beginning in 2008 to invest in renewable energy sources, reduce reliance on foreign oil, address global warming issues, and create jobs for Americans. The main objective for the New Energy for America plan was to implement clean energy sources in the United States in order to switch from nonrenewable resources to renewable resources. The plan led by the Obama Administration aimed to implement short-term solutions to provide immediate relief from pain at the pump, and mid- to- long term solutions to provide a New Energy for America plan. The goals of the clean energy plan hoped to: invest in renewable technologies that will boost domestic manufacturing and increase homegrown energy, invest in training for workers of the clean technologies, strengthen the middle class, and help the economy.
Solar power in California includes utility-scale solar power plants as well as local distributed generation, mostly from rooftop photovoltaics. It has been growing rapidly because of high insolation, community support, declining solar costs, and a Renewable Portfolio Standard which requires that 33% of California's electricity come from renewable resources by 2020, and 60% by 2030. Much of this is expected to come from solar power via photovoltaic facilities or concentrated solar power facilities.
The climate change policy of the United States has major impacts on global climate change and on global climate change mitigation. This is because the United States is the second largest emitter of greenhouse gasses in the world after China, and is among the countries with the highest greenhouse gas emissions per person in the world. In total the United States has emitted 400 billion metric tons of greenhouse gasses, more than any country in the world.
PACE financing is a means used in the United States of America of financing energy efficiency upgrades, disaster resiliency improvements, water conservation measures, or renewable energy installations of residential, commercial, and industrial property owners. Depending on state legislation, PACE financing can be used to finance building envelope energy efficiency improvements such as insulation and air sealing, cool roofs, water efficiency products, seismic retrofits, and hurricane preparedness measures. In some states, commercial PACE financing can also fund a portion of new construction projects, as long as the building owner agrees to build the new structure to exceed the local energy code.
The Green Deal was a UK government policy initiative that gave homeowners, landlords and tenants the opportunity to pay for energy efficient home improvements through the savings on their energy bills from 2012 to 2015. At the heart of the Green Deal was the rule that savings on bills would exceed the cost of the work. By meeting this 'Golden Rule', consumers were able to receive energy savings without direct cost. Consumers then paid back the cost of such improvements through the expected savings in their energy bills. However There is no guarantee that the eventual savings made by consumers will match the cost of the loans they take out to make the improvements and industry bodies recognised there was a risk consumers could end up out of pocket.
People of the State of California v. Federal Housing Finance Agency was a California state case in which several California-based plaintiffs filed suit against the Federal Housing Finance Agency (FHFA) for creating a lending rule that impeded the Property Assessed Clean Energy (PACE) program, a program in which property owners repay energy-related property improvements gradually over time as an addition to their property tax.
Public plans for energy efficient refurbishment are put in place by states to encourage building owners to renovate their properties in a way that increases their energy performance. As financing represents the most important obstacle to this type of renovation, the plans favour financial incentives in the form of loans or grants. Various institutions can be involved in the process, such as ministries, banks, firms, or energy services companies (ESCOs).
The HERO Program is an energy efficient financing program in the United States. The name HERO stands for Home Energy Renovation Opportunity. The HERO Program is a Property Assessed Clean Energy (PACE) Program, which provides financing for energy-efficient, water-efficient and renewable energy products to home and business owners in approved communities within California and Missouri. The financing provided by the HERO Program is repaid through annual property tax payments, which are collected by the County and in some cases may be passed on to a new property owner if the property is sold.
California has taken legislative steps in the hope of mitigating the risks of potential effects of climate change in California by incentives and plans for clean cars, renewable energy, and pollution controls on industry.
Home energy upgrades from public utilities are added home energy efficiency and renewable energy features planned or installed by public utilities. Help from a public utility can make it easier for a homeowner to select, install or operate climate-friendly components. The utility might assist with coordinated use of utility-supplied energy, building features, financing, operating options and neighborhood supplied energy.
