  • How an IIT Madras Initiative Is Powering 9,000 Homes at a Fraction of Traditional Electricity Costs

    A team of engineers at IIT Madras, a public university in India, has partnered with local utilities and the national Ministry of Power to bring sustainable, low-cost electricity to off-grid rural villages in the northwestern state of Rajasthan. With solar power supplied by DC microgrids, these poor rural communities are experiencing transformations to increase quality-of-life: affordable fridges that aid in food preservation, fans which mitigate heat and repel mosquitoes, and battery-powered phones connecting them to public emergency services.

  • Turning CO2 into stone in Iceland

    Iceland, hit by the oil crises of the 1970s, turned to geothermal energy - and they haven't turned back. The island is now powered by 100% renewable energy, and they are taking it one step more, looking to further cut emissions using a unique carbon capture system called CarbFix. It is being pioneered at the Hellsheidi geothermal power plant in western Iceland.

  • The Detroit Success Story Visible From Space

    In just three years, Detroit carried out an ambitious $185 million project to re-illuminate the city's 88,000 streetlights, half of which were dark, with new energy-efficient LED lights. Through its new Public Lighting Authority, the city used an innovative funding scheme to pay for the lights even in the midst of municipal bankruptcy. After the lights went up, residents felt safer, and businesses felt a noticeable bump.

  • Keeping it cool: Malaysia looks to district energy systems.

    A collaborative effort among the United Nations' District Energy in Cities Initiative, the Malaysian government, and private partners has facilitated planning in Malaysia's rapidly developing southern state of Johor for a "District Energy System": a single heating and cooling network which decreases energy consumption by converting waste heat from large power stations. Because of this intervention, Iskandar is projected to decrease its energy use by almost 40% -- all while saving money on energy costs, recycling heat energy, and contributing to the nation's goals under the international Paris Accord.

  • How A Man With No Coding Experience Built An App That's Bringing Solar Power To Yemen

    The civil war in Yemen caused the electrical grid to fail and left many in the country without reliable access to electricity. As Yemenis tried to implement solar power, many were finding the process difficult with nowhere to turn for answers. Anwar Al-Haddad couldn't find a solution for this growing problem, so he invented an app, despite a lack of coding knowledge, by using another app that had been invented in the Silicon Valley.

  • Northern Lights: Large-Scale Solar Power Is Spreading Across the U.S.

    Once largely confined to the desert Southwest, solar power is making its way across the United States. Due to decreasing prices in installations, coupled with government incentives and increasing knowledge of energy harvesting capabilities, solar has recently found its way into places such as Idaho, Maine, Alabama, Iowa, Kentucky, and Nebraska - with places like Georgia and Florida are looking to expand. Despite the pushback from the newest presidential administration, even cynics of the solar power movement are declaring it the most viable option.

  • Renewables roadshow: how the 'nonna effect' got Darebin's pensioners signing up to solar

    Although solar installations have been on the rise, it's often those that could most benefit from this renewable energy source that can't access it. The Darebin City Council in Australia recognized this challenge faced by very low-income households, and began what is now known as the Solar Saver program. Although it initially began as a way to help these families cut electricity costs, it is now focused on making solar more accessible by providing no cost installations and a 10-year payment plan that ultimately helps the families cut costs.
