Renewables booming but not enough to meet climate targets, U.N. says
11 6月 2020
The world added 12 percent more clean power capacity in 2019 than the year before, but new renewable energy planned over the next decade falls far short of what is needed to forestall dangerous global warming, the U.N. warned on Wednesday.
An additional 184 gigawatts of renewable power — mostly solar and wind — came on line last year, according to the Annual Global Trends in Renewable Energy Investment report, jointly issued by the U.N. Environment Program and Bloomberg New Energy Finance.
One gigawatt is similar to the capacity of a nuclear reactor.
Total investment in renewables in 2019 was $282.2 billion (¥30 trillion), led by China ($83.4 billion), the United States ($55.5 billion), Europe ($54.6 billion), Japan ($16.5 billion) and India ($9.3 billion), with a record 21 countries each spending at least $2 billion.
Developing nations — not including China and India — poured an unprecedented $59.5 billion into clean energy.
The rapidly falling cost of solar and wind power — less expensive in most electricity markets than coal — means more bang for the buck, the report showed.
Investment in 2019 was the same as the year before, but yielded an additional 20 GW of installed capacity.
But measured against the Paris climate treaty target of capping global warming at “well below” 2 C above pre-industrial levels, the transition to clean energy is not happening nearly fast enough, the report said.
The 826 GW of new renewables planned by 2030 — at a cost of about $1 trillion — is only a quarter of the roughly 3,000 GW required to keep us on track for a 2-C world, it concluded.
Investment is lagging as well — more than $2.7 trillion were committed to renewables during the last decade.
“Clean energy finds itself at a crossroads in 2020,” said BNEF chief executive Jon Moore, one of the report’s authors. “The last decade produced huge progress, but official targets for 2030 are far short of what is required to address climate change.”
When the current health crisis eases, he added, governments must not only boost renewable power, but the decarbonization of transport, buildings and industry.
The huge amounts of cash mobilized to jump-start economies stalled by COVID-l9 lockdowns is a once-in-a-generation opportunity to close this “renewables gap” in investment, the authors argue.
“If governments take advantage of the ever-falling price tag of renewables to put clean energy at the heart of COVID-19 economic recovery, they can take a big step towards a healthy natural world,” said UNEP executive director Inger Andersen.
“This is the best insurance policy against global pandemics.”
But the transition from a brown global economy to a green one is strewn with obstacles.
Investment in renewables last year, for example, was barely half the amount governments spent to subsidize fossil fuels, according to a report last week from the International Energy Agency and the Organization for Economic Co-operation and Development.
Combined subsidies for both consumption and production last year totaled $478 billion in 77 economies, the two intergovernmental agencies found.
That’s an 18 percent drop compared with 2018, but it was due mainly to lower oil and gas prices.
Indeed, subsidies for fossil fuel production in 44 countries increased 38 percent last year, OECD figures showed.
“I am saddened to see some backsliding on efforts to phase out fossil fuel support,” OECD Secretary-General Angel Gurria said in a statement.
