Renewable energy technology costs are dropping and capacity is increasing across end-use sectors and new geographies, especially in emerging markets. In 2010, renewable energy sources grew to supply an estimated 20 percent of global final energy consumption, and total investment in renewable energy reached $211 billion in 2010, up from $160 billion in 2009.
This increase was driven mainly by wind installations in China and small-scale rooftop PV in Europe. China also led investments, with almost $50 billion in new financing (not including small-scale projects and research and development). New markets are also quickly expanding, with 2010 being the first year in which new financial investments (not including small-scale projects and research and development) in the developing world outweighed those in the developed world.
Companies will need to continue to innovate and increase conversion efficiency of their products, but they will also have to compete on costs.
Advancements and innovations in renewable energy can be seen in many different industries:
-
Traditional oil and gas companies, such as Statoil, are investing heavily in renewable energy technologies such as offshore wind.
-
Electronics companies, such as Siemens, are building wind and solar technologies.
-
Chemical and biotechnology companies, such as Novozymes, are creating enzymes and feedstocks as inputs for biofuels renewable energy technologies.
-
Automobile companies, such as BMW, are investing in clean transportation technologies such as electric vehicles.
