Although world prices for fossil fuels are at 10- and 12-year lows and still falling, worldwide investment in renewable energy set records last year and is still growing, according to a fresh analysis from the respected Bloomberg New Energy Finance.
At nearly one-third of a trillion dollars – $328.9 billion, to be more precise – last year’s global outlays to expand solar, wind, biomass and small hydro capacity were up 4 percent from the previous year, up 3 percent from the previous record year (2011), and six times the total of just over a decade ago, in 2004.
In addition to low prices for conventional fuels, which in the U.S. are helping natural gas to kill coal plants and driving car shoppers back toward SUVs, the Bloomberg analysts found that three factors ought to have held down the global investment total last year – but didn’t.
Weakness in European economies that have been leading on renewables did rein in new investments, but not enough to offset surging gains elsewhere.
The strong U.S. economy should have reduced the dollar value of investments made in other currencies; similarly, falling prices for solar photovoltaic components should have made equivalent investments appear to be worth less over time, not more.
“These figures are a stunning riposte to all those who expected clean energy investment to stall on falling oil and gas prices,” said Michael Liebreich, chairman of the advisory board at Bloomberg New Energy Finance, in announcing the findings.
Wind and solar power are now being adopted in many developing countries as a natural and substantial part of the generation mix: they can be produced more cheaply than often high wholesale power prices; they reduce a country’s exposure to expected future fossil fuel prices; and above all they can be built very quickly to meet unfulfilled demand for electricity.
And it is very hard to see these trends going backwards, in the light of December’s Paris Climate Agreement.
Where are the new investments coming from, and why?
The Bloomberg analysis breaks the data down in multiple ways, defining “clean energy” to include wind, solar and biomass initiatives at various scales, from rooftop PV arrays to offshore wind farms, as well as hydroelectric plants with an output under 50 megawatts (MW).
(FWIW, a footnote in the analysis pegs new investment in large hydro during 2015 at $43 billion, which if counted would bump the global grand total by 13 percent, to $371.9 billion.)
Among nations, China was the world leader, and not for the first time; its overall clean-energy investment of $110.5 billion, up 17 percent from 2014, accounted for roughly one-third of the global total. Most of that went to wind and solar installations as the country tries to meet growing electric power demand while slowing the surge in air pollution from coal plants, which continue to proliferate.
No. 2 in the world was the United States, where investment rose 8 percent to $56 billion, the nation’s largest annual tally since 2011.

In Europe, investment was up in the UK (24 percent) but down in both Germany (42 percent) and France (53 percent). All in all, Europe’s total was down 18 percent from 2014 to a total of $58.5 billion, the lowest since 2006. Elsewhere, however,
Brazil’s clean energy investment slipped 10% to $7.5 billion in 2015, while India’s gained 23% to $10.9 billion, the highest since 2011 but a far cry for the figures needed to implement the Modi government’s ambitious plans. Japan saw investment rise 3% to $43.6 billion, on the back of a continuing PV boom. In Canada, clean energy investment fell 43% to $4.1 billion, while in Australia, it edged up 16% to $2.9 billion.
A number of “new markets” together committed tens of billions of dollars to clean energy last year. These include Mexico ($4.2 billion, up 114%), Chile ($3.5 billion, up 157%), South Africa ($4.5 billion, up 329%) and Morocco ($2 billion, up from almost zero in 2014).
Africa and the Middle East are two regions with big potential for clean energy, given their growing populations, plentiful solar and wind resources and, in many African countries, low rates of electricity access. In 2015, these regions combined saw investment of $13.4 billion, up 54% on the previous year.
By project type, Bloomberg found that more than half the world’s new clean energy investment went to “utility-scale projects such as wind farms, solar parks, biomass and waste-to-energy plants and small hydro-electric schemes.”
And among these, the biggest of the big were large offshore wind arrays in the North Sea and off the Chinese coast.
These included the UK’s 580 megawatt Race Bank and 336 MW Galloper, with estimated costs of $2.9 billion and $2.3 billion respectively, Germany’s 402MW Veja Mate, at $2.1 billion, and China’s Longyuan Haian Jiangjiasha and Datang & Jiangsu Binhai, each of 300MW and $850 million.
The biggest financing in onshore wind was of the 1.6 gigawatt Nafin Mexico portfolio, for an estimated $2.2 billion. For solar PV, it was the Silver State South project [in Nevada], at 294MW and about $744m, and for solar thermal or CSP, it was the NOORo portfolio in Morocco, at 350MW and around $1.8 billion. The largest biomass project funded was the 330MW Klabin Ortiguera plant in Brazil, which in addition to the construction of a 1.5-million-ton cellulose production plant, had a total investment of $2.3 billion, and the largest geothermal one was Guris Efeler in Turkey, at 170MW and an estimated $717 million.
However, smaller-scale and distributed generation projects also attracted investment of about $67.4 billion, or 12 percent more than in 2014; Japan was by far the biggest market for rooftop and other small-scale projects, followed by the U.S. and then China.
Grid-related investments in such items as utility-scale battery storage and “smart grid” control systems attracted $20 billion last year, up 11 percent. Research and development, both corporate and by governments, rounded out the list at $28.3 billion, just 1 percent higher than in 2014.

MinnPost event: On Monday, Feb. 22, MinnPost’s Earth Journal Circle will present its fourth annual event focusing on substantive discussion of critical issues in the environment. This year’s topic is “Land of 10,000 Lakes: Can We Achieve Water Sustainability?” The speaker is Deborah Swackhamer, former director of the University of Minnesota’s Water Resources Center, who will discuss issues threatening regional water quality and quantity. Earth Journal writer Ron Meador will moderate the Q&A session.
