Renewable energy commercializationRenewable energy commercialization involves the deployment of three generations of renewable energy technologies dating back more than 100 years. First-generation technologies, which are already mature and economically competitive, include biomass, hydroelectricity, geothermal power and heat. Second-generation technologies are market-ready and are being deployed at the present time; they include solar heating, photovoltaics, wind power, solar thermal power stations, and modern forms of bioenergy.
Renewable energyRenewable energy is energy from renewable resources that are naturally replenished on a human timescale. Renewable resources include sunlight, wind, the movement of water, and geothermal heat. Although most renewable energy sources are sustainable, some are not. For example, some biomass sources are considered unsustainable at current rates of exploitation. Renewable energy is often used for electricity generation, heating and cooling.
Energy Policy Act of 2005The Energy Policy Act of 2005 () is a federal law signed by President George W. Bush on August 8, 2005, at Sandia National Laboratories in Albuquerque, New Mexico. The act, described by proponents as an attempt to combat growing energy problems, changed US energy policy by providing tax incentives and loan guarantees for energy production of various types. The most consequential aspect of the law was to greatly increase ethanol production to be blended with gasoline.
Private equityIn the field of finance, private equity (PE) is an investment fund, usually a limited partnership, which invests in and restructures private companies. A private-equity fund is both a type of ownership of assets (financial equity) and is a class of assets (debt securities and equity securities), which function as modes of financial management for operating private companies that are not publicly traded in a stock exchange.
Private equity firmA private equity firm is an investment management company that provides financial backing and makes investments in the private equity of startup or operating companies through a variety of loosely affiliated investment strategies including leveraged buyout, venture capital, and growth capital. Often described as a financial sponsor, each firm will raise funds that will be invested in accordance with one or more specific investment strategies.
Angel investorAn angel investor (also known as a business angel, informal investor, angel funder, private investor, or seed investor) is an individual who provides capital to a business or businesses, including startups, usually in exchange for convertible debt or ownership equity. Angel investors often provide support to startups at a very early stage (when the risk of their failure is relatively high), once or in a consecutive manner, and when most investors are not prepared to back them.
InvestorAn investor is a person who allocates financial capital with the expectation of a future return (profit) or to gain an advantage (interest). Through this allocated capital most of the time the investor purchases some species of property. Types of investments include equity, debt, securities, real estate, infrastructure, currency, commodity, token, derivatives such as put and call options, futures, forwards, etc. This definition makes no distinction between the investors in the primary and secondary markets.
100% renewable energy100% renewable energy means getting all energy from renewable resources. The endeavor to use 100% renewable energy for electricity, heating, cooling and transport is motivated by climate change, pollution and other environmental issues, as well as economic and energy security concerns. Shifting the total global primary energy supply to renewable sources requires a transition of the energy system, since most of today's energy is derived from non-renewable fossil fuels.
Greenhouse gas emissionsGreenhouse gas emissions (abbreviated as GHG emissions) from human activities strengthen the greenhouse effect, contributing to climate change. Carbon dioxide (), from burning fossil fuels such as coal, oil, and natural gas, is one of the most important factors in causing climate change. The largest emitters are China followed by the US, although the United States has higher emissions per capita. The main producers fueling the emissions globally are large oil and gas companies.
Venture capitalVenture capital (commonly abbreviated as VC) is a form of private equity financing that is provided by venture capital firms or funds to startups, early-stage, and emerging companies that have been deemed to have high growth potential or which have demonstrated high growth (in terms of number of employees, annual revenue, scale of operations, etc). Venture capital firms or funds invest in these early-stage companies in exchange for equity, or an ownership stake.
