World clean energy investment totalled $333.5bn in 2017

Investment up 3% from 2016, second highest annual figure ever

An extraordinary boom in photovoltaic installations made 2017 a record year for China’s investment in clean energy. This overshadowed changes elsewhere, including jumps in investment in Australia and Mexico, and declines in Japan, the UK, and Germany, according to a recent report.


Annual figures from Bloomberg New Energy Finance (BNEF), based on its world-leading database of projects and deals, show that global investment in renewable energy and energy-smart technologies reached $333.5bn last year, up 3% from a revised $324.6bn in 2016, and only 7% short of the record figure of $360.3bn reached in 2015.


Jon Moore, chief executive of BNEF, commented: “The 2017 total is all the more remarkable when you consider that capital costs for the leading technology—solar—continue to fall sharply. Typical utility-scale photovoltaic (PV) systems were about 25% cheaper per megawatt last year than they were two years earlier.”

Solar investment globally amounted to $160.8bn in 2017, up 18% on the previous year despite these cost reductions. Just over half of that world total, or $86.5bn, was spent in China. This was 58% higher than in 2016, with an estimated 53 GW of PV capacity installed—up from 30 GW in 2016.

Justin Wu, head of Asia-Pacific for BNEF, said: “China installed about 20 GW more solar capacity in 2017 than we forecast. This happened for two main reasons: first, despite a growing subsidy burden and worsening power curtailment, China’s regulators, under pressure from the industry, were slow to curb the building of utility-scale projects outside allocated government quotas. Developers of these projects are assuming they will be allocated subsidy in future years.”

He continued, “second, the cost of solar continues to fall in China, and more projects are being deployed on rooftops, in industrial parks, or at other distributed locales. These systems are not limited by the government quota. Large energy consumers in China are now installing solar panels to meet their own demand, with a minimal premium subsidy.”

Overall, Chinese investment in all clean energy technologies was $132.6bn, up 24% and setting a new record. The next biggest investing country was the US at $56.9bn, up 1% in 2016 despite the less friendly tone towards renewables adopted by the Trump administration.

Large wind and solar project financings pushed Australia up 150% to a record $9bn, and Mexico up 516% to $6.2bn. On the downside, Japan saw investment decline by 16% in 2017, to $23.4bn, while Germany slipped 26% to $14.6bn, and the U.K. 56% to $10.3bn in the face of changes in policy support. Europe as a whole invested $57.4bn, down 26% year-over-year.


Solar led the way, as mentioned above, attracting $160.8bn—equivalent to 48% of the global total for all clean energy investment. The two biggest solar projects of all to get the go-ahead last year were both in the United Arab Emirates: the 1.2 GW Marubeni-JinkoSolar project and ADWEA-Sweihan plant, at $899m, and the 800 MW Sheikh Mohammed bin Rashid Al Maktoum III installation, at an estimated $968m.


Wind was the second-biggest sector for investment in 2017, at $107.2bn. This is down 12% from 2016 levels, but there were record-breaking projects financed both onshore and offshore. Onshore, American Electric Power said it would back the 2 GW Oklahoma Wind Catcher project in the US at $2.9bn, excluding transmission. Offshore, Ørsted said it had reached “final investment decision” on the 1.4 GW Hornsea 2 project in the UK’s North Sea, at an estimated $4.8bn. There were also 13 Chinese offshore wind projects financed last year, with total capacity of 3.7 GW, and estimated investment of $10.8bn.


The third-biggest sector was energy-smart technologies, where asset finance of smart meters and battery storage, and equity-raising by specialist companies in smart grid, efficiency, storage, and electric vehicles reached $48.8bn in 2017, up 7% on the previous year and the highest ever.


The remaining sectors lagged far behind, with biomass and waste-to-energy down 36% at $4.7bn, biofuels down 3% at $2bn, small hydro 14% lower at $3.4bn, low-carbon services 4% down at $4.8bn, geothermal down 34% at $1.6bn, and marine energy down 14% at just $156m.

The clean energy investment total excludes hydroelectric projects of more than 50 MW. However, for comparison, final investment decisions in large hydro are likely to have been worth $40-50bn in 2017.

BNEF’s preliminary estimates are that a record 160 GW of clean energy-generating capacity (excluding large hydro) were commissioned in 2017, with solar providing 98 GW of that, wind 56 GW, biomass and waste-to-energy 3 GW, small hydro 2.7 GW, geothermal 700 MW, and marine less than 10 MW.

Breaking the investment total down by type of deal, the dominant category—as always—was asset finance of utility-scale renewable energy projects of more than 1 MW. This was $216.1bn in 2017, up fractionally on the previous year. Small-scale projects of less than 1 MW (effectively small solar systems) attracted $49.4bn, up 15%—thanks in large part to the installation rush in China.

Equity-raising by specialist clean energy companies on public markets totalled $8.7bn in 2017, down 26%. The biggest transactions in this category were a $978m convertible issue by electric car maker Tesla, and a $545m placement by Guodian Nanjing Automation, a Chinese technology supplier to generating and transmission plants.
