The year 2008 was the best yet for renewables. Even though the global economic downturn affected renewables in many ways starting in late 2008, the year was still one to remember. As Table 1, on page 22, shows, in just one year, the capacity of utility-scale solar photovoltaic (PV) plants (larger than 200 kW) tripled to 3 GW. All forms of grid-tied solar PV grew by 70%. Wind power grew by 29% and solar hot water increased by 15%. Annual ethanol and biodiesel production both expanded by 34%. Heat and power from biomass and geothermal sources continued to grow, and small hydro increased by 8%.
