The role of developing countries in promoting the development of renewable energy, the role of developing countries is growing: China's market growth ahead of the world; India's existing wind power capacity in the world ranked fifth, and is rapidly expanding in many forms Rural renewable energy, such as biogas and solar photovoltaic power generation; Brazil is the world leader in sugarcane ethanol, and is also adding new biomass and wind power facilities. In addition, renewable energy markets in other developing countries such as Argentina, Costa Rica, Egypt, Indonesia, Kenya, Tanzania, Thailand, Tunisia, and Uruguay are all experiencing rapid growth.
Renewable energy has now entered an era of geographical diversity. For example, wind power generation only existed in a few countries in the 1990s, and currently 82 countries around the world carry out this business. In addition to Europe and the United States, developed countries such as Australia, Canada, and Japan 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 It is also very active.
At the same time, renewable energy-related manufacturing is moving from Europe to Asia, such as China, India, and South Korea. In 2009, Chinese companies produced 40% of the world's total solar photovoltaic cells, 30% of global wind turbines (only 10% in 2007), and solar hot water collectors accounted for 77% of the world's total.
The government has increased 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 introduced some renewable energy incentive policies. However, since the new century, more countries and local governments have introduced relevant support policies, and many countries have set renewable energy use countries. The goal is to specify that a significant portion of electricity will come from renewable sources by 2020, which is more than 10% to 50%. China's goal is to reach 15% of final energy consumption from renewable energy sources by 2020.
According to statistics, by September 2010, at least 83 countries have issued relevant policies to promote renewable energy power generation. The 10 most common types of policies are access tariffs, renewable energy use standards, investment subsidies or grants, investment tax credits, sales tax or value-added tax incentives, green certificate transactions, direct energy production payments or tax credits, net measures , direct public investment or financing, and open competitive bidding.
There are also many countries that have adopted policies to support the use of renewable heat. For example, some countries or their local governments have issued directives for the promotion and application of solar water heaters for new buildings. Israel is the only country that sets a national directive in this regard. Spain also passed in 2006. National building codes require that solar thermal systems in new buildings and renovations must meet 30% to 70% of hot water demand.
In the transportation sector, many countries have issued directives to blend biofuels into vehicle fuels, and some countries have proposed several goals and plans for the future use of biofuels. Countries with production or use targets include the United States, the United Kingdom, Japan, China, and South Africa. The EU’s goal is that by 2020, renewable fuels account for 10% of transport energy, involving sustainable biofuels and electric vehicles.
Investment continues to maintain its strong growth The growth of investment in the renewable energy sector by the public sector, venture capital and development banks has undoubtedly greatly promoted the development of the industry. Excluding major hydropower projects, the global investment in renewable energy in 2009 was approximately US$150 billion, breaking the record of US$130 billion in 2008. In 2009, the world's investment in wind power reached 62.7 billion U.S. dollars, a substantial increase from the 55.5 billion U.S. dollars in 2008. Most of the increase in wind energy investment was caused by China’s rapid expansion, coupled with increased investment activity in the wind power industry in Latin America and the commissioning of large offshore wind farms in the UK.
Germany and China were the leading countries for investment in 2009. The two countries invested 25 to 30 billion U.S. dollars in renewable energy, including small hydropower projects; followed by the U.S., and invested more than 15 billion U.S. dollars; Italy and Spain accounted for 4 billion U.S. dollars. 5 billion U.S. dollars.
Oil Mist Separator to solve the machine tool industry, the bearing industry, cleaning industry and those high-speed cutting industry in the production of fog control processing.This series of products USES the advanced oil mist separation technology, adopts the five-level filtration technology, the quick lock fastening maintenance and repair is convenient, adopts the reliable processing technology, creates the same kind of products in the fine, the performance is consistent with the import but the price is lower than the import price.
Working principle:
Centrifuge high-speed negative pressure produced by the rotation of the pollutants within the suction machine, after the first level stainless steel net coarse filter, filtering and then the secondary, tertiary, into the centrifugal fan, will play to the walls of water mist to form water, the remaining gas from behind again after secondary filtration, separation, purification processing and oil and air to separation, purification of air through the air hole, oil and water after a specified line.
