The hottest renewable energy in the world continue

Global renewable energy continues to grow significantly

developed countries lead developing countries to follow up the renewable energy policy in the 21st century. The 2010 global renewable energy situation released at the end of September this year requires that some special problems should be considered when measuring fracture mechanics parameters: the report points out that despite the challenges brought about by the global financial crisis, the decline in oil prices and the slow progress of climate change policies, In 2009, the global investment in renewable energy power generation continued to grow, and the importance of renewable energy is growing

the role of developing countries is improving

in promoting the development of renewable energy, the role of developing countries is growing: China's market growth is leading the world; India's existing wind power generation capacity ranks fifth in the world, and giving full play to the experience and resource platform advantages of multinational companies, it is rapidly expanding various forms of rural renewable energy, such as biogas and solar photovoltaic power generation; Brazil leads the world in sugarcane ethanol, and is also adding new biomass and wind power facilities. In addition, the renewable energy markets of Argentina, Costa Rica, Egypt, Indonesia, Kenya, Tanzania, Thailand, Tunisia, Uruguay and other developing countries are growing at a relatively rapid rate

renewable energy has entered an era of regional diversity. For example, wind power generation only existed in a few countries in the 1990s, and currently 82 countries around the world have carried out this business. In addition to Europe and the United States, Australia, Canada, Japan and other developed countries have recently witnessed significant growth in renewable energy and expanded technological diversification; Renewable energy markets in more than 20 developing countries in the Middle East, North Africa and sub Saharan Africa are also very active

at the same time, renewable energy related manufacturing is shifting from Europe to Asia, such as China, India and South Korea. In 2009, the solar photovoltaic cells produced by Chinese enterprises accounted for 40% of the global total, wind turbines accounted for 30% of the global total (only 10% in 2007), and solar water heater collectors accounted for 77% of the global total

the government should increase policy support

the development of renewable energy cannot be separated from policy support. In the 1980s and early 1990s, only a few countries in the world, including 178000 tons of lithium carbonate capacity, introduced some renewable energy incentive policies. However, since the new century, more national and local governments have introduced relevant support policies, and many countries have set national targets for renewable energy utilization, stipulating that a considerable part of electricity will come from renewable energy by 2020, which is mostly 10% - 50%. China has set a goal that by 2020, 15% of the final energy consumption will come from renewable energy

according to statistics, by September 2010, at least 83 countries had introduced relevant policies to promote renewable energy power generation. The 10 most common policy types are input electricity price, renewable energy use standard, investment subsidy or appropriation, investment tax credit, sales tax or value-added tax preferential relief, green certificate transaction, direct energy production payment or tax credit, net measurement, direct public investment or financing, and open competitive bidding

many countries also adopt policies to support the utilization of renewable heat energy. For example, some countries or their local governments have issued directives on the promotion and application of solar water heaters required for new buildings. Israel is the only country that has set national directives in this regard. Spain also passed the national building code in 2006, requiring that the solar thermal system in new buildings and reconstruction must meet 30% - 70% of the hot water demand

in the field of transportation, many countries have issued directives to integrate biofuels into vehicle fuels, and some countries have put forward several goals and plans for the use of biofuels in the future. Countries with production or use targets include the United States, Britain, Japan, China and South Africa. The EU's goal is that by 2020, renewable fuels will account for 10% of transportation energy, involving sustainable biofuels and electric vehicles

investment still maintained a strong growth trend

the growth of investment in renewable energy by the public sector, venture capital and development banks undoubtedly greatly promoted the development of the industry. Excluding large hydropower projects, the global investment in renewable energy in 2009 was about US $150billion, breaking the record of US $130billion in 2008. In 2009, the global investment in wind energy reached US $62.7 billion, a sharp increase from US $55.5 billion in 2008. Most of the growth in wind energy investment is due to the rapid expansion of capacity in China, coupled with increased investment activities in the Latin American wind power industry and the investment of large offshore wind power plants in the UK

Germany and China were investment leaders in 2009, and their investment in renewable energy, including small hydropower projects, was $25billion to $30billion; The second is the United States, with an investment of more than $15billion; Italy and Spain are US $4billion to US $5billion
