  • Chimney Sweeps Attack Deadly Pollution Crisis

    After banning the burning of raw coal as a way to reduce air pollution in Mongolia, residents of Ulaanbaatar switched to refined charcoal to heat their homes. However, that coal also wasn’t the cleanest and contributed to hundreds suffering from carbon monoxide poisoning. To fix that, the government teamed up with a private company to hire more than 1,600 people to clean and inspect people’s chimneys and stoves. While critics say the program doesn’t solve the country’s pollution problem, the service has provided jobs to those who didn’t have steady work and helped those who aren't able to clean their stoves.

  • How sunshine can make the railways greener

    As a way to reduce the amount of diesel fuel that powers trains, governments and transit companies around the world are turning to solar panels as a way to utilize renewable energy. In Australia, a solar train launched in 2017 that uses lithium-ion batteries that are charged by solar panels on the roof of the carriages. And a rail line in the United Kingdom uses energy from a solar farm to keep the train running. Scaling solar panels for nation-wide transit systems can be challenging, but many countries are committed to eliminating the use of fossil fuels on their rail networks.

  • Crowdfunded solar puts Red Lake Nation on a path to energy sovereignty

    The Red Lake Nation in Minnesota is building a 240-kilowatt solar array on top of a workforce training center, which will generate about half of the building’s electricity. This project was financed through crowdfunding, where they raised $250,000 from religiously inclined microlenders. The goal: to allow the tribe to have energy sovereignty, create higher-paying jobs, and maintain a healthy environment.

  • Yemen's ‘microgrid girls' power community amid war and COVID-19

    A solar-grid station is powering rural Yemeni communities on the front-line of the war and in the midst of COVID-19, while also empowering women who typically have very few professional opportunities. The microgrid project supplies the community with affordable and clean energy, replacing expensive diesel generators which are bad for the environment. Electricity bills have been cut by 65 percent, an impressive gain in one of the world's poorest country. Thousands of entrepreneurs have generated income based on the new electricity source and many more have benefitted from new services and products available.

  • ‘Energy Aggregation' Has the Potential to Transform How We Get Power, But Hurdles Remain Audio icon

    California communities are turning to “community choice aggregators,” which allows them to buy electricity from green providers and have more control over the energy grid. However, the financial pressure for these programs to offer competitive rates as public utilities can mean that the programs might increase their dependence on cheaper, less green energy sources. So far, 21 of these community-choice programs are in the Golden State, serving 10 million customers.

  • Smart Tourism

    Tourists can travel to remote destinations in the Himalayas and help install solar technology in villages where residents live without electricity. GHE has used funds from the tourism component to electrify 100 villages which increased the quality of life for residents and resulted in an opportunity for tourism where one did not exist before. As a result of the electrification, a community tourism initiative allowed for tourists to stay with villagers and provided an addition source of income. The economic stimulus from tourism gave native youth a reason to stay in their villages instead of migrating.

  • Locals Question the Relevance of First Solar Power Plant in Soroti

    Four years later after a solar grid was installed in Uganda, residents of nearby villages are wondering when they will get some of that power. The 10-megawatt facility, which cost $19 million to build, was expected to provide electricity to about 40,000 homes, schools, and businesses in the area. However, almost all households in the 10 surrounding villages still use firewood for cooking. The lessons learned from this renewable energy project could help inform others as the country looks to power more parts of the country with solar panels.

  • In Slumping Energy States, Plugging Abandoned Wells Could Provide an Economic Boost

    North Dakota is using some of its COVID-19 pandemic relief funds to plug 239 abandoned oil wells and reclaim 2,000 acres of lands. Abandoned wells can contaminate groundwater and leak methane that is hazardous to human health and contributes to climate change. While not everyone agrees that the funds should be used to plug wells, state officials say the economic relief program is keeping about 600 oilfield workers employed.

  • Bitcoin Miner Is Scoring 700% Profits Selling Energy to Grid

    A cryptocurrency mining company in Texas called Layer1 can power down its data-processing centers and sell its unused electricity back to the power grid. Instead of passively consuming energy, they are able to utilize batteries, smart meters, and artificial intelligence software to use more renewable energy and, at the same time, make a profit. While scaling this response can be difficult due to restrictions from utility companies on how consumers get their energy, Layer1 estimates it will save up to $6.7 million annually by cutting production for 30 minutes during some of the hottest days in the summer.

  • Can we harness the Arctic's methane for energy?

    Alternative energy systems in Africa could help inform how to trap methane in the Arctic. Due to permafrost thawing and glaciers melting, methane, a greenhouse gas that contributes to climate change, is leaking into the atmosphere. In Rwanda, a lake-based methane power plant extracts methane from the water and turns it into electricity. But questions remain about how similar systems and infrastructure could work in the Arctic landscape.
