World's Biggest Coal Company Closes 37 Mines as Solar Prices Plummet

The rapid growth in renewable energy continues to put a dent in the demand for coal.

Coal India, the world's biggest coal mining company and producer of 82 percent of the country's coal, announced the closure of 37 mines that are financially "unviable."


The sites make up roughly nine percent of the total mines operated by Coal India. The company is expected save Rs 800 crore ($124 million) from the closures.

India's energy market is undergoing a rapid transformation as it moves away from fossil fuels. Last month, the country cancelled plans to build nearly 14 gigawatts of coal-fired power stations.

Notably, solar has been cheaper than coal-based electricity in India for the past several months. According to Quartz:

"At an auction for 500 megawatt (MW) of capacity at the park on May 12, the state-run Solar Energy Corporation of India (SECI) managed to discover a record-low tariff of Rs 2.44 per kilowatt-hour (kWh). The previous low was two days before that when tariffs hit Rs 2.62 per kWh during auctions for another phase of Bhadla solar park.

"The country's largest power company, NTPC, sells electricity from its coal-based generation units at a princely Rs 3.20 per kWh."

The National Thermal Power Corporation of India said that the country currently hosts a solar power capacity of 845 megawatts, after the recent addition of a 225 megawatt solar farm, the Mandsaur Solar Power Project.

"India's solar sector has received heavy international investment, and the plummeting price of solar electricity has increased pressure on fossil fuel companies in the country," as The Independent reported. "The government has announced it will not build any more coal plants after 2022 and predicts renewables will generate 57 percent of its power by 2027—a pledge far outstripping its commitment in the Paris climate change agreement."

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.

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.

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."
