Authoritative annual data, published by Bloomberg New Energy Finance, show that global investment in clean energy was $310bn last year. This was up 16% from a revised $268.1bn in 2013, and more than five times the figure of $60.2bn attained a decade earlier, in 2004, albeit still 2% below the all-time record of $317.5bn reached in 2011.
The jump in investment in 2014 reflected strong performances in many of the main centres for clean energy deployment, with China up 32% to a record $89.5bn, the US up 8% to $51.8bn (its highest figure since 2012), Japan up 12% to $41.3bn, Canada up 26% at $9bn, Brazil up 88% at $7.9bn, India up 14% to $7.9bn, and South Africa up 5% at $5.5bn. Europe, despite the flurry in offshore wind, was a relative dull spot overall, investment there edging 1% higher to $66bn.
Many big solar and onshore wind projects around the world were also financed in 2014. They included the Setouchi Mega PV project in Japan, at an estimated $1.1bn for 250MW, the Xina Solar One solar thermal plant in South Africa, at $1bn for 100MW, the $859m, 310.5MW Lake Turkana wind project in Kenya and the K2 wind complex in Ontario, Canada, at $728m and 270MW.
The second-largest category of investment was small distributed capacity – projects of less than 1MW, predominantly rooftop solar. This saw $73.5bn committed in 2014, up 34%. Research and development by governments and corporations totalled $29bn, some 2% more than in 2013, while asset finance of energy smart technologies such as smart meters came in at $16.8bn, up 8% on 2013.
New equity raised for clean energy companies on public markets hit a seven-year high in 2014, at $18.7bn, up 52% on the year. US electric car maker Tesla Motors raised $2.3bn via convertible issues, and a succession of US- and UK-listed “yieldcos” and project funds tapped investors for $3.9bn in total.
Venture capital and private equity investment in clean energy was $4.8bn in 2014, up 16% on the year but still far below the $12.3bn record set in 2008.
The increased total for public market and VC/PE investment came despite a 3% slippage in clean energy share prices over the year. The WilderHill New Energy Global Innovation Index, or NEX, which tracks the just over 100 stocks worldwide, peaked at 220.58 in March 2014 and slid to 178.66 by year-end.
Solar made up almost half of total clean energy investment in 2014, its highest share ever. Last year, solar saw $149.6bn committed, up 25% on 2013. Investment in wind rose 11% to a record $99.5bn. The third largest sector was energy smart technologies, including smart grid, power storage, efficiency and electrified transport, with $37.1bn of investment, up 10%. Investment in biofuels was just $5.1bn in 2014, down 7%, and in biomass and waste-to-energy $8.4bn, down 10%. Geothermal attracted $2.7bn, up 23% on 2013, while small hydro-electric (projects of less than 50MW) got $4.5bn, down 17%.
