Press Release

World investment in clean energy in 3Q 2018 was at $67.8 billion, down 6% from the same period in 2017. The slip in the July-September quarter leaves investment for the year so far running a modest 2% below that in the first nine months of 2017 – leaving open the possibility that 2018 as a whole will end up matching last year’s total.

What the 2017 data shows

BNEF figures show dollar clean energy investment rising in 2017, with an extraordinary boom in photovoltaic installations in China driving the surge. These are the key highlights:

1. Overall investment is up by 3%.

New investment in clean energy reached $333.5 billion last year, up 3% from a revised $324.6 billion in 2016, and only 7% short of the record figure of $360.3 billion, reached in 2015.

2. Solar costs continue to fall sharply.

Typical utility-scale PV systems were about 25% cheaper per megawatt last year than they were two years earlier. Solar investment globally amounted to $160.8 billion in 2017, up 18% on the previous year despite these cost reductions.

3. China sets new record for clean energy investment.

Overall, Chinese investment in 2017 across all the clean energy technologies was $132.6 billion, up 24%, setting a new all-time record. The next biggest investing country was the U.S., at $56.9 billion, up 1% on 2016. In third place, Japan saw investment decline by 16% in 2017, to $23.4 billion.

4. More clean energy commissioned than ever before.

Preliminary estimates show that a record 160GW of clean energy generating capacity (excluding large hydro) were commissioned globally in 2017, with solar providing 98GW of that capacity, and wind 56GW.

5. VC and PE investments cool down.

Venture capital and private equity investment in clean energy amounted to $4.1 billion in 2017, down 38% on the previous year and the lowest figure since 2005.

6. Clean energy acquisition activity at highest level ever.

This totaled $127.9 billion in 2017, up 4% on the previous year and the highest ever. Behind this surge were a rise in renewable energy project acquisitions and refinancing to $87.2bn, and a sixfold leap in private equity buy-outs to $15.8bn.
