Cheap wind power is making dams more valuable as a ‘battery’

CBC News / Don Pittis / 8 February 2021

The cost of wind and solar power have fallen so much over the last decade that they are much cheaper than building new hydroelectric dams — “The cost declines have been astounding,” said Carlson — but they have the disadvantage of being intermittent.

“The sun doesn’t shine at night,” he said someone always tells him on Twitter when he mentions solar’s cost advantages, “As if I weren’t aware of that.”

The advantage of combining less-expensive intermittent power with Quebec’s existing system of hydroelectric power dams is that it allows the power utility to use up the cheap wind power as it is produced while the water behind the dams is retained, at the ready.

Oil and gas know-how looks to alternatives in business-led push

CBC News / Don Pittis / 20 November 2020

A series of private sector-led projects in Alberta and Saskatchewan are evidence that profit-motivated entrepreneurs have already seen which way the wind is blowing.

Even as jobs disappear from the traditional fossil fuel sector, a new report from the University of Calgary’s School of Public Policy says the plunging cost of alternative power is helping to stoke a low-carbon investment boom.

“This suggests building new renewables is now cheaper than operating existing fossil power plants,” the University of Calgary report said. And the first signs of that boom are already appearing.

Solar is now ‘cheapest electricity in history’, confirms IEA

Carbon Brief / Josh Gabbatiss, Simon Evans / 13 October 2020

The world’s best solar power schemes now offer the “cheapest…electricity in history” with the technology cheaper than coal and gas in most major countries.

That is according to the International Energy Agency’s World Energy Outlook 2020. The 464-page outlook, published today by the IEA, also outlines the “extraordinarily turbulent” impact of coronavirus and the “highly uncertain” future of global energy use over the next two decades.

Reflecting this uncertainty, this year’s version of the highly influential annual outlook offers four “pathways” to 2040, all of which see a major rise in renewables.

Court reverses move by Ford government to cancel wind farm

Globe and Mail / Jeff Gray / 14 May 2020

An Ontario court has struck down a move by the provincial government to kill the partly-built Nation Rise Wind Farm southeast of Ottawa, quashing Environment Minister Jeff Yurek’s decision last year to block the project over his concerns about endangered bats.

In its ruling, the Ontario Divisional Court said Mr. Yurek’s decision last December was “not reasonable,” and did not “meet the requirements of transparency, justification, and intelligibility.” Instead of returning the matter to the minister for reconsideration, the court took the unusual step of quashing it altogether and allowing construction on the wind farm to resume.

Review: Planet of the Humans

Post Carbon Institute / Richard Heinberg / 27 April 2020

The film is controversial because it makes two big claims: first, that renewable energy is a sham; second, that big environmental organizations—by promoting solar and wind power—have sold their souls to billionaire investors.

I feel fairly confident commenting on the first of these claims, regarding renewable energy, having spent a year working with David Fridley of Lawrence Berkeley National Laboratory to assess the prospects for a complete transition to solar and wind power.

We found that the transition to renewables is going far too slowly to make much of a difference during the crucial next couple of decades, and would be gobsmackingly expensive if we were to try replacing all fossil fuel use with solar and wind.

World’s wind power capacity up by fifth after record year

The Guardian / Jillian Ambrose / 25 March 2020

The world’s wind power capacity grew by almost a fifth in 2019 after a year of record growth for offshore windfarms and a boom in onshore projects in the US and China.

The Global Wind Energy Council found that wind power capacity grew by 60.4 gigawatts, or 19%, compared with 2018, in one of the strongest years on record for the global wind power industry.

The growth was powered by a record year for offshore wind, which grew by 6.1GW to make up a tenth of new windfarm installations for the first time.

The council’s annual report found that the US and China remain the world’s largest markets for onshore wind power development. Together the two countries make up almost two-thirds of global growth in wind power.

The Transition Framework

Resilience is the ability of a system or community to withstand impacts from outside. An indicator is a good way of measuring that. Conventionally, the principal way of measuring a reducing carbon footprint is CO2 emissions. However, we firmly believe that cutting carbon while failing to build resilience is an insufficient response when you’re trying to address multiple shocks such as peak oil, climate change and the economic crisis together.
