Portugal Joins Other Countries by Running Only on Renewable Energy

Portuguese architecture
Portugal reached a very significant milestone on its path to being fully powered by renewables by consuming energy only from sustainable resources for four days. Other countries are on similar paths. In 2012 Germany got 50% of it’s power from renewable sources, Scotland powered itself exclusively on renewables for a week earlier this year, but the most impressive is Costa Rica. In 2015 Costa Rica went at least of a quarter of the using only renewables and improving this year.

Portugal joins those countries (and others) that are looking forward to a future that isn’t dependent on finite energy sources. More countries should be joining this renewable revolution.

Electricity consumption in the country was fully covered by solar, wind and hydro power in an extraordinary 107-hour run that lasted from 6.45am on Saturday 7 May until 5.45pm the following Wednesday, the analysis says.

News of the zero emissions landmark comes just days after Germany announced that clean energy had powered almost all its electricity needs on Sunday 15 May, with power prices turning negative at several times in the day – effectively paying consumers to use it.

Scotland Generated Enough Renewable Energy to Power Itself

This past weekend Scotland generated enough electricity from wind turbines to meet all its power demands. A day of strong winds and low demand combined to make this the first time Scotland has achieved this renewable milestone. For a compression, in 2012 Germany got 50% of it’s electricity from renewable sources, and today Germany gets almost all of its power from renewable sources on a regular basis. In a couple years Scotland could be 100% powered by renewables. The cost of solar and wind installations continues to fall so it’s likely more regions of the world will be able to follow Scotland’s lead.

“It should also be remembered that wind power is not the only renewable power source Scotland has at its disposal.

“If we continue to take steps to reduce our energy demand, invest in storage, and increase our use of renewables we can hopefully look forward to many days that are fully powered by nature.”

The figures showed that wind turbines in Scotland provided 39,545 megawatts per hour (MWh) of electricity to the National Grid for 24 hours on Sunday. Scotland’s total electricity consumption for that day was 37,202MWh. It is unclear whether demand at any single point in the day exceeded the amount supplied by the turbines.

Canadian Government Think Tank: Renewables Win Over Fossil Fuels


When the Conservatives were in charge of Canada they didn’t conserve at all, instead they rallied behind fossil fuels to power Canada’s economy. That foolish gamble contributed to a lame economy (sent the country into massive debt) and a dying planet (even sabotaging global discussions about carbon and fossil fuel. Canadians are hopeful that the new government led by the Liberals will reverse the Conservatives anti-common sense approach to energy policy.

Last week, a federal think tank release a report on the near term growth of Canada’s economy and global influence. They project that fossil fuels will be less important to the global economy with every passing year and that the benefits of switching to renewable energy for the planet are obvious.

At the core of the report’s forecasts is a growing number of indicators that suggest growth in the world’s demand for electricity — particularly renewable-based electricity — will outpace other energy types, while the costs of its production and storage fall faster than previously believed.

The demand is expected to be driven largely by the emerging and rapidly urbanizing middle class in developing countries.

Wind and solar systems have the advantage of being “highly scalable and distributable,” the report states, making them appealing for communities of virtually any size, with or without an existing electrical grid.

As a result, emerging economies in Latin America and Africa may follow a different development path than the West and “leap-frog” directly to renewables as a primary energy source in a relatively short timeframe.

The Unstoppable Renewable Revolution

For years naysayers have been arguing that renewable energy isn’t a good idea because the electrical input fluctuates too much on the grid. Now we have more evidence that those naysayers have nothing to back up their argument.

Over at Climate Progress they have a good post on key factors that make the renewable revolution unstoppable. One reason is the ability of technology to make up for perceived (and in some cases, real) shortcomings of renewable energy production.

A key point, though, is that new technology is increasingly making it less and less likely for there to be an unexpectedly cloudy or windless day. As a 2014 article on “Smart Wind and Solar Power” in Technology Review put it, “Big data and artificial intelligence are producing ultra-accurate forecasts that will make it feasible to integrate much more renewable energy into the grid.”

It’s already happening: “Wind power forecasts of unprecedented accuracy are making it possible for Colorado to use far more renewable energy, at lower cost, than utilities ever thought possible.” The National Center for Atmospheric Research (NCAR) in Boulder makes these forecasts “using artificial-intelligence-based software … along with data from weather satellites, weather stations, and other wind farms in the state.” And that helped Xcel Energy, a major power producer in the state, set a remarkable record in 2013 — “during one hour, 60 percent of its electricity for Colorado was coming from the wind.”

Solar and Wind Continue to Succeed, Coal Keeps Failing

Coal continues its downward trend to obsolescence thanks to the rise of installed solar and wind capacity. In many places around the world coal is more expensive than renewable energy and as a result it has driven costs down elsewhere.

The future is clearly one that won’t use coal as an energy resource. We need to keep the carbon in the ground, and we’re slowly starting to leave coal alone.

For the first time, widespread adoption of renewables is effectively lowering the capacity factor for fossil fuels. That’s because once a solar or wind project is built, the marginal cost of the electricity it produces is pretty much zero—free electricity—while coal and gas plants require more fuel for every new watt produced. If you’re a power company with a choice, you choose the free stuff every time.
It’s a self-reinforcing cycle. As more renewables are installed, coal and natural gas plants are used less. As coal and gas are used less, the cost of using them to generate electricity goes up. As the cost of coal and gas power rises, more renewables will be installed.
