Wind Energy Could Generate Nearly 20 Percent of World's Electricity by 2030

Wind power has a pivotal role to play in the world's energy supply over the next few years. By providing huge amounts of clean, affordable power, it can buy us time in the fight against global warming while revolutions in energy efficiency and solar power gain momentum.

Wind power could be supplying up to 19 percent of the world's electricity and avoiding over three billion tonnes of CO2 a year by 2030. By 2050, 25-30 percent of global power could come from harnessing the wind. Photo credit: Karuna Ang / Greenpeace

Greenpeace and the Global Wind Energy Council have just released a two-yearly status report on wind energy and its prospects up to 2050.

In as little as five years' time wind power could prevent more than a billion tons of carbon dioxide (CO2) from being emitted each year by dirty energy. That's equivalent to Germany's and Italy's emissions combined, or Africa's total CO2 emissions, or those of Japan, or two-thirds of what India pumps out.

Ten years after that, wind power could be supplying up to 19 percent of the world's electricity and avoiding more than three billion tons of CO2 a year. By 2050, 25-30 percent of global power could come from harnessing the wind.

The wind industry has grown at around 26 percent per year over the past 18 years. Europe and China have been solid wind markets for over a decade.

Now the U.S. is on the way to gaining a 20 percent share of the world market. In the coming five years, the rapidly developing economies of Brazil, South Africa and India are likely to be among the next to reap the benefits of wind power.

The main reason for this is that wind power has become the least-cost option for adding new power capacity to the grid in an increasing number of markets. Prices are continuing to fall and smart investors are seizing on the potential. During each of the past four years, an average of €50 billion went into new wind power equipment. This could increase to €104 billion by 2020 and €141 billion by 2030, according to the status report.

There is also good news for jobs. Around 600,000 people currently work in the wind power industry. That figure could rise to around 1.5 million by 2020 and exceed 2 million jobs by 2030.

But what also makes wind power attractive is its 'scalability' and the speed that power can be brought on line. That's particularly important where people have no access to electricity. Contrast that with huge and highly controversial coal-fired or nuclear power plants that involve years of debate and construction.

(By the way, forget the claim by sceptics that more energy is used in manufacturing wind turbines than they supply. A wind turbine 'pays back' all of the carbon dioxide emissions from its manufacturing, installation, servicing and decommissioning in its first three to nine months of operation. That means pollution-free power for the rest of its 20-year design lifetime).

Why all this is important is because the power sector pumps out more than 40 percent of all CO2 emissions from burning fossil fuels.

Wind power is an ideal technology to achieve early reductions in carbon pollution and to keep the window open to avoid global warming crossing the 2°C 'danger' threshold. But time is short for meeting climate protection targets and ensuring that global emissions peak and decline during this decade.

Capturing all of the future opportunities for wind power will once again depend on convincing recalcitrant policymakers and overcoming the vested interests of the fossil fuel lobby.

Slaughter of 90,000 Wild Horses Could Proceed Despite 80% Objection From American Public

The American Wild Horse Campaign on Thursday harshly criticized Interior Sec. Ryan Zinke's appointment of Brian Steed, the former chief of staff for U.S. Rep. Chris Stewart (R-UT), as the acting director of the Bureau of Land Management (BLM) as dangerous and out of step with the wishes of the vast majority of Americans.

"Rep. Stewart is leading the charge to slaughter America's wild horses and burros over the opposition of 80 percent of Americans," said Suzanne Roy, AWHC Executive Director. "Putting his deputy at the helm of the agency charged with protecting these national icons is like putting the wolf in charge of the chicken coop."

Bright Idea: This Lamp Harvests Its Own Energy From Plants

Now that's green energy. Dutch product designer Ermi van Oers and her team are working on the first atmospheric lamp powered by living plants.

The Living Light does not require an electric socket. It can harvest its own energy through the photosynthetic process of the encased plant, which means the potential of this off-grid light source could be "huge," as Van Oers told Dezeen.

Pope Francis: These 4 'Perverse Attitudes' Could Push Earth to Its Brink

Pope Francis issued a strong message to negotiators at the COP23 climate talks in Bonn, Germany on Thursday, warning them not to fall into "four perverse attitudes" regarding the future of the planet—"denial, indifference, resignation and trust in inadequate solutions."

Francis, who has long pressed for strong climate action and wrote his 2015 encyclical on the environment, renewed his "urgent call" for renewed dialogue "on how we are building the future of the planet."

Groups Sue Norway Over Failure to Protect Environment for Future Generations

By David Leestma

Greenpeace and the Nature and Youth environmental group opened a lawsuit this week over Norway's failure to abide by its constitutional obligation to safeguard the environment for future generations.

The lawsuit, which focuses on local environmental damage and the contribution that oil extraction will make to climate change, challenges 10 licenses issued by the Norwegian government for exploration in the Barents Sea. Given to Statoil, Chevron and other oil companies, the licenses violate Norway's constitution and the Paris agreement, according to the plaintiffs. Government lawyers claim the case is a publicity stunt that risks valuable jobs.

A Plea for Kelp: These Farmers and Chefs Want to Make Seaweed the Next Superfood

By Sarah Bedolfe

Summer in southeast Alaska is kelp season for the cofounders of Barnacle Foods, Lia Heifetz and Matt Kern. Each week, the pair watches the tides and weather, waiting for the right moment to cruise out to the abundant kelp beds offshore. They lean over the side of the boat and pull up the fronds and stalks, one piece at a time. As soon as they get back to shore, they start processing the day's harvest into a local delicacy: kelp salsa.

Salsa and Alaskan algae might seem like odd bedfellows, but for Barnacle Foods, it's a calculated decision. The kelp's savory notes make the salsa's flavor "a little more explosive," according to Kern. And the pairing is also a practical one. "Salsa is such a familiar food item," Heifetz said. It's "a gateway to getting more people to eat seaweed."
