In recent years, the economy significantly improved solar power technology. Since 2010, investment levels have dropped 70% solar power units. The next 5-10 year, solar power will cost with fossil fuels or even lower. To reduce global carbon emissions target, 2050 global solar power is expected to generate around 35%, becoming one of the dominant energy.
Since 2000, the global solar power capacity grew quickly, with an average annual growth rate reached 46.9%, ranks first in the various types of renewable energy. By the end of 2014, global solar power installed capacity reached 180 million kW, are mainly located in Germany, China, Japan and the United States, and Italy and other equatorial countries other than, about 94.7%. Solar energy development in the equatorial region smaller, generation capacity accounted for 5.3%. Great potential for solar energy development in the equatorial region of the future.
3. q: Equatorial areas suitable for building solar-powered base?
Answer: according to the report, North Africa, South Asia, North America, South America and West of Australia, are more suitable for development and construction of solar-powered base.
Selection principle of the solar Base: climate-appropriate, available, close to major transmission channel, good infrastructure. Researchers say that, combined with the solar resource assessment results from all continents, short and medium term recommendations developed tropical desert climate regions of large solar plants, as North Africa solar base, Western Asia Solar base, solar-powered base on the West side of South America and Australia solar energy base. In consideration of the difficulty of construction and operation and maintenance, this study does not consider the desert solar energy development.
˙ North Africa solar base
North Africa populated coastal zone and inland is the Sahara desert. North Africa solar base consists mainly of Western base, Central bases East and Al-Qaeda, three solar-powered base.
˙ Western solar base in Asia
Solar power base is located in the Arabian Peninsula East, along the Persian Gulf, including Saudi Arabia a small area in the East, U.A.E. and Oman East, mainly to coastal plains and desert areas, sufficient water resources.
˙ Solar energy in South America base
Solar-powered base is located in Peru and southern Chile North Pacific Coast narrow areas, taking into account the Andes, the city, the impact of mining areas, limited actual development area.
˙ Australia solar energy base
Solar-powered base located near Darwin in the Northern Prairie region, is rich in water resources, the terrain is relatively flat.
˙ Solar energy in southern North America base
Solar, based in Mexico, Chihuahua and the United States, and Mexico border Highlands, intensity of solar radiation is North America’s largest region, tremendous potential for development.
4. what future, solar power, where you can enjoy the Equator?
Answer: Europe, Asia, South America, Africa, Oceania and so on, were able to enjoy the Equatorial solar cleaning power.
Based on the pattern of global renewable energy development and utilization research, North Africa solar solar base, Western Asia solar energy base, South America base and Australia solar base priority power delivered to the land, to minimize the distance across the sea and the overall transmission distance, guaranteed transmission technology economy.
North Africa solar base power will main sent European, and through Asia West area and Asia Networking; South America solar base main to East of Brazil load Center area transmission; Asia West solar base while to population many of South Asia transmission, while and North area connected, became connection Asia, and European, and Africa of important hub; Australia solar base will through series Pacific island chain, to population many, and resources lack of Southeast Asia area transmission.
By the above construction of transmission channels, can not only solve solar power delivery problems in the equatorial region, and can realize the related continents in the northern hemisphere and South power grid interconnection, using the time difference and the difference Gets the networking benefits of the season. In addition, through the solar base can also build in Western Asia South corridor linking Eurasian power.
5. question: development of solar energy resource in the equatorial region which bonus will be released?
A: development of solar energy resource in the equatorial region, not only is the best promotion of sustainable social development and solve environmental problems, and drive the growth of the world economy and promote regional peace, powerful starting point for achieving global prosperity.
Development of solar energy in the equatorial region, will contribute to energy and sustainable development of human society.
On one hand, to meet the power demand of the local economic and social development, promoting local economic development. In addition, the power of mass, distance to the major load centers around the world, driving regional economic development with resource development, on the realization of economic, social and energy environment of harmonious development, COP21 global carbon emission control targets set by the General Assembly is of great significance.
The equatorial regions except Australia in addition to other countries are developing countries, regional economy will continue to develop rapidly in the future, will face rigid power consumption growth stage. The power structure dominated by fossil fuels in developing countries and regions, and most are in tight supply problems, Africa, about 600 million people without electricity. In the context of global efforts to combat climate change and development, vigorously develop renewable resources such as solar, seize the development opportunity, is not only a resource for economic growth, narrow the gap between the North and the important strategic opportunity and realize common prosperity in the world and protect the local power supply to achieve “renewable energy for all” important measures to achieve global objectives on climate change an important choice.
The Equator on solar power, can be expected.
The Equator on solar power, is based on the theoretical research and practice of strategic thinking.
At present, on the base of solar energy development in the equatorial region, has been a lot of study and basic, such as North Africa desert solar project, the trans-Asian energy infrastructure concepts, power interconnection systems in the Andean countries. Meanwhile, developed the Equatorial solar plants, and power transmission to the load centers with better economic competitiveness. Also, load centers dominated by terrestrial channel to the northern hemisphere in the equatorial region, existing ± 1100 economic range of UHV DC transmission technology, technical no obstacles.
Develop the Equatorial solar not just a thing of a nation, in the face of North Africa, the Middle East complex of geo-politics and international relations, we also need to address the technical and economic issues at the same time, establishing mechanisms for cooperation and win-win development, promote regional States in the development of renewable energy and promoting regional economic development, achieving the global targets for cooperation.
