The average of renewable energy in the European Union (EU-28) increased by 0.7% to 15.0% compared to 2012. These methods include promoting renewable sources such as solar power and wind power, requiring utilities to use more renewable energy, and providing tax incentives to encourage the development and use of such technologies. Bioenergy is renewable energy made available from materials derived from biological sources. "Some countries are eliminating or reducing climate-disrupting subsidies and Belgium, France, and Japan have phased out all subsidies for coal. Use of wind power in 2012 increased by 18.1 percent, to 521.3 TWh.The incentive to use 100% renewable energy for electricity, transport, or even total primary energy supply globally, has been motivated by At the national level, at least 30 nations around the world already have renewable energy contributing more than 20% of energy supply. Since policies are not self-implementing, energy sector regulators become a key facilitator (or blocker) of renewable energy investments.Germany has made significant progress on its GHG emissions reduction target, achieving a 27% decrease between 1990 and 2014. "The price of PV modules per MW has fallen by 60 percent since the summer of 2008, according to Bloomberg New Energy Finance estimates, putting solar power for the first time on a competitive footing with the retail price of electricity in a number of sunny countries. Despite abundant natural resources and a relatively small population, New Zealand is a net importer of energy, in the form of petroleum products. Benjamin K. Sovacool.

According to the 2013 Moving towards energy sustainability will require changes not only in the way energy is supplied, but in the way it is used, and reducing the amount of energy required to deliver various goods or services is essential. It also contributed about $3.5 billion in tax revenues at the local, state, and federal levels".Third-generation renewable energy technologies are still under development and include advanced First proposed more than thirty years ago, systems to harvest utility-scale electrical power from ocean waves have recently been gaining momentum as a viable technology. Fridleifsson, I.B., R. Bertani, E. Huenges, J. W. Lund, A. Ragnarsson, and L. Rybach (2008). India is ranked fourth in wind power, fifth in solar power and fifth in renewable power installed capacity as of 2018. Opportunities for improvement on the demand side of the energy equation are as rich and diverse as those on the supply side, and often offer significant economic benefits.A sustainable energy economy requires commitments to both renewables and efficiency. There are now three hydroelectricity plants larger than 10 GW: the Geothermal power capacity grew from around 1 GW in 1975 to almost 10 GW in 2008.Geothermal (ground source) heat pumps represented an estimated 30 GWth of installed capacity at the end of 2008, with other direct uses of geothermal heat (i.e., for space heating, agricultural drying and other uses) reaching an estimated 15 GWth. A 2011 IEA report said: "A portfolio of renewable energy technologies is becoming cost-competitive in an increasingly broad range of circumstances, in some cases providing investment opportunities without the need for specific economic support," and added that "cost reductions in critical technologies, such as wind and solar, are set to continue. China is the largest hydroelectricity producer, with 721 terawatt-hours of production in 2010, representing around 17 percent of domestic electricity use. China, Germany, the United States, Italy, and Brazil.The solar PV market has been growing for the past few years. China cut its coal subsidy from $750 million in 1993 to $240 million in 1995 and more recently has imposed a high-sulfur coal tax.A fair and efficient imposition of subsidies for renewable energies and aiming at sustainable development, however, require coordination and regulation at a global level, as subsidies granted in one country can easily disrupt industries and policies of others, thus underlining the relevance of this issue at the World Trade Organization.Setting national renewable energy targets can be an important part of a renewable energy policy and these targets are usually defined as a percentage of the primary energy and/or electricity generation mix.

The subsidy dropped from $5.4 billion in 1989 to $2.8 billion in 2002, and in the process Germany lowered its coal use by 46 percent. The use of fracking in natural gas exploration is coming under scrutiny, with evidence of groundwater contamination and greenhouse gas emissions. As per the European Union's 200 Norway is Europe's largest producer of hydropower and the 6th largest in the world. Many policies distort the market in favour of existing fossil fuel technologies.Fossil-fuel energy systems have different production, transmission, and end-use costs and characteristics than do renewable energy systems, and new promotional policies are needed to ensure that renewable systems develop as quickly and broadly as is socially desirable.Tax shifting has been widely discussed and endorsed by economists. Jeff Scruggs and Paul Jacob. Voluntary green power products must offer a significant benefit and value to buyers to be successful.
