Scaling up technologies key to combating climate change will take anywhere between 18 years to more than 100, the International Energy Agency found in a recent report.

Why it matters: Scientists say the world must find ways to drastically cut heat-trapping emissions over the next 30 years, but the path of innovating and scaling is stubbornly long, even in the best of scenarios.

Unions are going offshore to find a receptive renewable energy.

Driving the news: America’s nascent offshore wind industry, which requires uniquely complex infrastructure, is being built out with strong labor agreements that were largely absent from their onshore counterparts.

Rapidly falling offshore wind power prices in key European markets could also bode well for the emerging U.S. sector, according to findings from a peer-reviewed study in Nature Energy.

Why it matters: This is a turning point in the economics of offshore wind — a potentially massive source of carbon-free power.

European Union power generation from renewables exceeded fossil fuel-based electricity for the first time in the first half of 2020, per new analysis Wednesday from the U.K.-based climate think tank Ember.

Why it matters: It appears to be an inflection point. Ember electricity analyst Dave Jones tells Axios that he does not expect fossil generation to regain a bigger share than renewables.

Joe Biden’s latest climate change and clean energy plan mentions the word union more than it does the climate itself.

Why it matters: Wind and solar energy have grown immensely across America over the last decade, but associated union jobs have not. The Democrats’ presumptive presidential nominee is trying to change that, which politicians and others say is key to tackling climate change.

A big rise in offshore wind power deals pushed global investment in new renewable power capacity in the first half of 2020 above the same period last year, new data shows.

Why it matters: It signals how the renewables sector as a whole has proven rather resilient to the pandemic, despite some declines in onshore wind and solar investment, BloombergNEF analysts said.

The head of House Democrats' climate change panel has a simple reason why their wide-ranging plan includes nuclear power despite misgivings in some corner of the left.

What they're saying: “That’s what the scientists advised as we listened across the spectrum, that’s where we landed — that nuclear power needs to be part of the portfolio going forward,” Rep. Kathy Castor said on the new episode of the Columbia Energy Exchange podcast.

Sunrun, the largest U.S. home solar provider, is buying rival Vivint Solar in a $3.2 billion all-stock transaction, the companies announced Monday.

Why it matters: The deal between major players brings new consolidation to the U.S. solar sector, a growing market that has been hindered by the coronavirus pandemic.

Europe is facing pressure to include natural gas and nuclear power as part of its plan for sustainable finance.

Why it matters: Europe represents the progressive edge of the world’s response to climate change and controls a lot of finance in developing nations, so what it does on these controversial energy sources could set the bar globally.

Amazon is creating a $2 billion venture fund that will stake companies working on climate-friendly technologies in transportation, storage, food, power generation, waste and more, the tech giant said Tuesday.

Why it matters: The new fund will help Amazon and other companies meet the "climate pledge" that Amazon announced last year to reach net-zero emissions by 2040.
