The year 2009 was unprecedented in the history of renewable energy, despite the headwinds posed by the global financial crisis, lower oil prices, and slow progress with climate policy.
Indeed, as other economic sectors declined around the world, existing renewable capacity continued to grow at rates close to those in previous years, including grid-connected solar PV (53 %), wind power (32 %), solar hot water/heating (21 %), geothermal power (4 %), and hydropower (3 %). Annual production of ethanol and biodiesel increased 10 % and 9 %, respectively, despite layoffs and ethanol plant closures in the United States and Brazil. Download the report here.
