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.
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.

Shower shoes? Check. Extra-long sheets? Yep. Energy efficiency checklist? No worries — we've got you covered there. If you're one of the nation's 12.1 million full-time undergraduate college students, you no doubt have a lot to keep in mind as you head off to school. If you're reading this, climate change is probably one of them, and with one-third of students choosing to live on campus, dorm life can have a big impact on the health of our planet. In fact, the annual energy use of one typical dormitory room can generate as much greenhouse gas pollution as the tailpipe emissions of a car driven more than 156,000 miles.

Kokia drynarioides is a small but significant flowering tree endemic to Hawaii's dry forests. Native Hawaiians used its large, scarlet flowers to make lei. Its sap was used as dye for ropes and nets. Its bark was used medicinally to treat thrush.
States that invest heavily in renewable energy will generate billions of dollars in health benefits in the next decade instead of spending billions to take care of people getting sick from air pollution caused by burning fossil fuels, according to a new study from MIT and reported on by The Verge.
Hawaii's Kilauea volcano could be gearing up for an eruption after a pond of water was discovered inside its summit crater for the first time in recorded history, according to the AP.

From where I stand inside the South Dakota cornfield I was visiting with entomologist and former USDA scientist Jonathan Lundgren, all the human-inflicted traumas to Earth seem far away. It isn't just that the corn is as high as an elephant's eye — are people singing that song again? — but that the field burgeons and buzzes and chirps with all sorts of other life, too.
Humanity faced its hottest month in at least 140 years in July, the US National Oceanic and Atmospheric Administration (NOAA) said on Thursday. The finding confirms similar analysis provided by its EU counterparts.

Indonesia's president has made permanent a temporary moratorium on forest-clearing permits for plantations and logging.
It's a policy the government says has proven effective in curtailing deforestation, but whose apparent gains have been criticized by environmental activists as mere "propaganda."
