World's Second Largest Source of Electricity Is Now Renewables

It probably surprises nobody to learn that coal produces more of the world’s electricity than any other fuel. But it may provide food for thought to realize that the second most widely-used fuels for power generation are now renewables.

Electricity generation from renewable sources has overtaken natural gas to become the second largest source of electricity worldwide, the International Energy Agency (IEA) has announced.

In Europe, the main renewables used to generate electricity are wind and solar power. Since 1990, global solar photovoltaic power has been increasing at an average growth rate of 44.6 percent a year and wind at 27.1 percent.

The IEA reports that electricity production last year in the 34 members of the Organization for Economic Co-operation and Development (OECD) fell slightly to 10,712 TWh (terawatt hours)—a decrease of 0.8 percent (86 TWh) compared with 2013. To put that in context, 1 TWh is 1 billion kilowatt hours and each KWh takes about 0.36 kilograms of coal to generate.

Partially Offset

This decline, the agency says, was driven by lower fossil fuel and hydro production, which were only partially offset by increases in non-hydro renewables. These grew by 8.5 percent and nuclear energy by 0.9 percent.

In 2014, solar photovoltaic power overtook solid biofuels—used in power plants that burn biomass—to become the second-largest source of non-hydro renewable electricity in OECD countries of Europe, with a share of 17.3 percent.

The IEA says overall growth in electricity generation continues to be driven by non-OECD countries. Its latest statistics, which show world electricity generation increasing by 2.9 percent between 2012 and 2013, reveal two distinct trends.

Electricity generation is leveling off within the OECD, while it is rising strongly in the rest of the world. In 2011, non-OECD countries for the first time produced more electricity than members of the OECD.

Other milestones were reached in 2013, when global non-hydro renewable electricity exceeded oil-fired generation for the first time and renewable electricity overtook natural gas to become the world’s second largest source of electricity, producing 22 percent of the total.

In the same year, electricity generated by coal reached its highest level yet at 9,613 TWh, representing 41.1 percent of global electricity production. The growth in coal generation was driven by non-OECD countries.

Globally, more renewable energy is consumed in the residential, commercial and public services sectors than elsewhere, but there are two distinct patterns of use.

In non-OECD countries, only 22.3 percent of renewables are used for electricity and heat production and 60.7 percent in homes, commercial and public sectors. In OECD countries, more than half of the renewable primary energy supply (58.5 percent) is used for electricity and heat.

Huge Challenge

The IEA’s data will encourage renewable energy’s supporters, but they also show how much the world continues to rely on fossil fuels for its electricity.

In 1971, coal produced about 2 TWh of global electrical power, but that figure is now almost five times higher. Replacing that much generation with clean fuels will be a huge challenge, despite the very rapidly accelerating growth of renewables.

Fatih Birol, the IEA’s director, has said that, without clear direction from the UN climate summit to be held in Paris in December, "the world is set for warming well beyond the 2°C goal,"—the internationally-agreed limit for global temperature rise that is intended to prevent climate change reaching dangerous levels.

The IEA World Energy Outlook 2014 said that, by 2040, the world’s energy supply mix is likely to divide into four almost-equal parts: oil, gas, coal and low-carbon sources.

This scenario, it said, "puts the world on a path consistent with a long-term global average temperature increase of 3.6°C."

Britain's Prince William interviewed famed broadcaster David Attenborough on Tuesday at the World Economic Forum's annual meeting in Switzerland.

During the sit-down, the 92-year-old naturalist advised the world leaders and business elite gathered in Davos this week that we must respect and protect the natural world, adding that the future of its survival—as well as humanity's survival—is in our hands.

Electric vehicle sales took off in 2018, with a record two million units sold around the world, according to a new Deloitte analysis.

What's more, the accounting firm predicts that another 21 million electric cars will be on the road globally over the next decade due to growing market demand for clean transportation, government subsidies, as well as bans on fossil fuel cars.

Plastic pollution in the world's oceans has become a global environmental crisis. Many people have seen images that seem to capture it, such as beaches carpeted with plastic trash or a seahorse gripping a cotton swab with its tail.

As a scientist researching marine plastic pollution, I thought I had seen a lot. Then, early in 2017, I heard from Alex Weber, a junior at Carmel High School in California.

Greenland is melting about four times faster than it was in 2003, a new study published Monday in the Proceedings of the National Academy of Sciences found, a discovery with frightening implications for the pace and extent of future sea level rise.

"We're going to see faster and faster sea level rise for the foreseeable future," study lead author and Ohio State University geodynamics professor Dr. Michael Bevis said in a press release. "Once you hit that tipping point, the only question is: How severe does it get?"

Finally, some good news about the otherwise terrible partial government shutdown. A federal judge ruled that the Trump administration cannot issue permits to conduct seismic testing during the government impasse.

The Justice Department sought to delay—or stay—a motion filed by a range of coastal cities, businesses and conservation organizations that are suing the Trump administration over offshore oil drilling, Reuters reported. The department argued that it did not have the resources it needed to work on the case due to the shutdown.

Most people have heard of the Amazon, South America's famed rainforest and hub of biological diversity. Less well known, though no less critical, is the Pantanal, the world's largest tropical wetland.

Like the Amazon, the Pantanal is ecologically important and imperiled. Located primarily in Brazil, it also stretches into neighboring Bolivia and Paraguay. Covering an area larger than England at more than 70,000 square miles, the massive wetland provides irreplaceable ecosystem services that include the regulation of floodwaters, nutrient renewal, river flow for navigability, groundwater recharge and carbon sequestration. The wetland also supports the economies of the four South American states it covers.

Organizers said 35,000 people marched through the streets of the German capital on Saturday to say they're "fed up" with industrial agriculture and call for a transformation to a system that instead supports the welfare of the environment, animals and rural farmers.

If you have ever considered making the switch to an environmentally friendly electric vehicle, don't drag your feet. Though EV prices are falling, and states are unveiling more and more public charging stations and plug-in-ready parking spots, the federal government is doing everything it can to slam the brakes on our progress away from gas-burning internal combustion engines. President Trump, likely pressured by his allies in the fossil fuel industry, has threatened to end the federal tax credits that have already helped put hundreds of thousands of EVs on the road—a move bound to harm not only our environment but our economy, too. After all, the manufacturing and sale of EVs, hybrids, and plug-in hybrids supported 197,000 jobs in 2017, according to the most recent U.S. Energy and Employment Report.
