Renewable energy is a source of energy that can never be exhausted.
We can obtain renewable energy from the sun (solar energy), from the water (hydropower), from the wind (windmills), from hot dry rocks, magma, hot water springs (geothermal) and even from firewood, animal manure, crop residues and waste (Biomass).

In the June 2007 issue of the China Renewable Energy and Sustainable Development Report from Lou Schwartz, recent developments in renewable energies in China offer insight into that country's burgeoning challenges between population, energy and the environment.
"Between 2005 and 2030, China will account for 23% of the world's investment in power, spending $1.2 trillion U.S.D. in that period."
-- China Renewable Energy and Sustainable Development Report, June 2007
The report cites that the "Persistent rural poverty in China and periodic power shortages all have impressed upon Beijing that renewable energy must be a large part of China's economy if China is to both complete its economic transformation and achieve energy security."
"Between 2005 and 2030, China will account for 23% of the world's investment in power, spending $1.2 trillion U.S.D. in that period," Schwartz notes. "China's ambitious growth target for renewable energy production will require an investment of approximately 800 billion Yuan (~$100 billion U.S.D.) by 2020. In the long term China has set an objective of having 30% or more of its total energy requirements satisfied by renewable sources by 2050."
Current business opportunities, foreign participation, relevant conferences, and production and consumption are also discussed in this month's China Renewable Energy and Sustainable Development Report.
The in-depth report examines developments across China's renewable energy industry, as seen in these excerpts:
- Solar: "The Chinese government has recently announced that large new buildings will all utilize photovoltaic power generating technology."
- Wind: "Researchers at the Jiangsu Province Macroeconomic Research Institute have advocated that large-scale wind power should be directly used to provide electric power to industries, which are large consumers of power."
- Hydropower: "In 2007 there will be another 500 MW of small to medium sized hydroelectric power generating capacity constructed in Guangxi Province."
- Biomass, Biofuels: "China hasn't yet standardized its macro-economic policies with respect to the bio-diesel industry, but it is now formulating and will soon..."
- Laws and Policies: "These sets of issues include the fact that there are more than 10 million Chinese who do not have access to electric power and the often-spotty access to power among tens of millions of other rural Chinese."
