Heating with coal, oil and natural gas accounts for around a quarter of global greenhouse gas emissions. But that's something we can change, says Wolfgang Feist, founder of the Passive House Institute in the western German city of Darmstadt.
Germany's financial capital has big environmental plans.
The Swiss city of Schaffhausen is among the growing number of municipalities using heat pump technology.
Experts and environmentalists are calling for a ban on the installation of new polluting heating systems.

Renewable sources of electricity are set for rapid growth over the next five years, which could see them match the output of the world's coal-fired power stations for the first time ever.

Costa Rica aims to have net zero carbon emissions by 2050 and if it's energy production in 2019 is a sign of things to come, then it is well on its way to that goal. The small Central American nation produced the most electricity in its history during the month of May and nearly 100 percent of it was from renewable sources, according to Think Geoenergy.
The birthplace of coal power is changing its ways. For the first time since the industrial revolution, the United Kingdom will generate more electricity from clean energy sources like wind, solar and nuclear power rather than from fossil fuel plants, the country's National Grid said Friday, as the BBC reported.

What's the future of coal? The answer may be blowing in the wind. Or running through our waters. Or, maybe it's at the end of a sunbeam.
Wherever the answer is found, the message is clear. Coal is on a downward trend in the U.S. and renewables are on the rise, according to a new report released by the Federal Energy Regulatory Commission, or FERC.
A solar weather monitoring station looms over an old coal strip mine in the heart of coal country, Somerset County, PA, with the Casselman Wind Farm spinning in the background. The station collects data for a proposed utility-scale solar array at this site.

Thousands of hydroelectric dams are under construction around the world, mainly in developing countries. These enormous structures are one of the world's largest sources of renewable energy, but they also cause environmental problems.
The dammed Fuerto and Santiago Rivers show greater erosion where they reach the Pacific coast than the free-flowing San Pedro and Acaponeta rivers. Images at right show coastline changes during the two periods: blue indicates land accretion, red indicates erosion.

Only a little more than one-third of the world's 246 longest rivers remain free-flowing, drastically reducing the diverse benefits that healthy rivers provide to people and nature everywhere, according to a new study by World Wildlife Fund (WWF) and partners.

5: Priority recommendations that the U.S. Environmental Protection Agency (EPA) has implemented since March 2018. Those actions relate to chemical standards, nonpoint water pollution and water pollution assessment. There are, however, 14 priority recommendations that the agency has not acted on.

Over the past 25 years that I have been conducting environmental research in the Amazon, I have witnessed the the ongoing destruction of the world's biggest rainforest. Twenty percent of it has been deforested by now—an area larger than Texas.
I therefore grew hopeful when environmental policies began to take effect at the turn of the millennium, and the rate of deforestation dropped from nearly 11,000 square miles per year to less than 2,000 over the decade following 2004.

A pair of "French spies" had infiltrated India by sea to commit a "treasonous conspiracy," an Indian minister claimed in late November. In reality, they were two visiting journalists, and their mission was an investigation into allegations of illegal sand mining in the southern state of Tamil Nadu. They had merely tried and failed to visit the site of a major mining company through legal means.
Their presence set off alarm bells among some connected to the industry, and the fallout has been significant. It's included a police investigation, a politically fueled propaganda campaign and the arrests of two local translators who had been working for them.
The total available capacity from wind, solar, biomass, hydro and other renewables reached a record 42 gigawatts between July and September, overtaking the 40.6 gigawatts available from fossil fuels, according to a report commissioned by Drax's Electric Insights and produced by Imperial College London researchers.
This year's Living Planet Report shows that populations of animals—including mammals, birds, fish, reptiles and amphibians—plummeted by 60 percent between 1970 and 2014. But those living in freshwater are experiencing a far more drastic decline: 83% since 1970. It's a sobering statistic and one tied directly to the ever-increasing pressures that people are putting on natural habitats.
