In the face of greenhouse gas emissions , global climate change , ecological and environmental damage and energy consumption growth , energy transformation has become a matter closely linked with each country and humankind of the earth . The world is in a new era of energy transformation . The basic feature of the energy transformation is to reduce greenhouse gas emissions , develop high proportion of renewable energy and improve energy efficiency , of which high proportion of renewable energy development is an important symbol of this energy transformation , while wind , solar , biomass and other renewable energy will play an important role in energy transformation .

In 2014 , the global wind power market started to climb up , the newly installed wind power capacity reached 52.52 GW , and the cumulative installed wind power capacity reached 371.335 GW , so wind power capacity had accounted for around 4 % of the world ’ s electricity supply . In 2014 , China continued to lead the global wind power market , the newly installed wind power capacity accounted for 45.2 % of that of world , and the cumulative installed wind power capacity accounted for 31 % of that of world . In 2014 , the most newly installed wind power capacity region was Asia , 26.161GW , followed by the Europe 12.820GW . In addition , the wind power markets of Africa , North America and Australia have also shown slow growth . According to preliminary statistics , the first half

of 2015 global wind power installed capacity is close to 20 GW , more than 10 % bigger than in 2014 . In a recent report 2015 World Energy Outlook released by the International Energy Agency ( IEA ), known for its underestimation of renewable energies , shows that by 2030 renewable energy will become the world ’ s most major power generation . The IEA predicts its proportion of the world ’ s total power generating capacity to increase up to 33 % - all past IEA predictions have been exceeded by far . Therefore , the future of wind power market will continue to maintain growth momentum .

Climate change has been a threat to public health , happiness and security . Actively respond to climate change , get a significant reduction in greenhouse gas emissions , and promote the development of low-carbon energy has become a national policy of different national governments . In November of 2014 , the governments of China and U . S . reached an agreement on achieving the goal of carbon emission peak value by 2030 . G7 summit of this year proposed by 2050 , global greenhouse gas emissions will be reduced by about 70 % and a full decarburization to be achieved by end of the century ; by the end of 21st century global economy will achieve the two goals of carbonization . At present , the global greenhouse gas emissions mainly come from energy production and utilization , accounting for about 2 / 3 , therefore , in order to achieve the goal of greenhouse gas emissions , we must change the current energy structure , the important sign of the reform is to achieve a high proportion of renewable energy development , and gradually form a renewable energy-oriented , multiple , low-carbon and safe energy system . The United States and Germany proposed that by 2050 80 % electricity will come from renewable energy , France and Australia also proposed that by 2050 100 % electricity will come from renewable energy , Israel proposed by 2040 , renewable energy in the proportion of the energy structure reached 80 % or more , Saudi Arabia will get rid of the dependence on fossil energy in 2040 . China put forward in a study report about high proportion of renewable energy development situation and path that the proportion of renewable energy will reach 62 %.

High proportion of renewable energy development will get rid of fossil energy dependence step by step , which has become the basic mode of future energy supply and consumption , high proportion of renewable energy development will further promote the global economic and social development , promote new industries , promote energy technology progress , expand employment , and achieve harmony between humankind ,

humankind and nature , humankind and society , build a beautiful earth , it is the dream of all human beings .

At present , global renewable energy in the process of sustainable development is still facing many constraints , which needs all countries to work together to cope with . To this end , the World Wind Energy Association made the following suggestions :

1 . High proportion of renewable energy development requires international community to build a scientific renewable energy development strategy planning and objective , also on the basis of a signed global climate change agreement . Governments should have a stable policy environment and regulations supporting , increase investment in renewable energy and promote energy transformation .

2 . Wind energy will be an important part of high proportion of renewable energy development . Wind energy utilization requires sophisticated system engineering , and it will be integrated into the whole energy system to plan and implement , and wind energy should have synergetic development with other renewable energy . We should adapt to the development of a new round of industrial revolution , making full use of information technology to explore new business models and market mechanisms , improving energy efficiency , and reducing the cost of power generation .

3 . Wind energy has no borders . Utilizing wind power and protecting the earth is the common goal of all mankind . Governments have the responsibility to raise public awareness of renewable energy utilization . Wind energy has no borders , we should make sure the role of non-governmental organizations in various countries are given full play , and use the established exchange platform and the cooperation agreement between governments to further strengthen international cooperation and exchanges , especially developed countries should actively support the technological progress and capacity building in developing countries . While focusing on the development of large-scale renewable energy , we also need to address the needs of poor areas to develop distributed and small and medium renewable energy systems , expand renewable energy investment projects and achieve win-win cooperation .
