Forests shaped more by Native Americans’ burning

Native Americans' use of fire to manage vegetation in what is now the Eastern United States was more profound than previously believed, according to a Penn State researcher who determined that forest composition change in the region was caused more by land use than climate change. "I believe Native Americans were excellent vegetation managers and

India 2024: An energised India

Providing affordable and accessible energy to every citizen while ensuring energy security has been the cornerstone of India’s energy policy. Over the years, this policy has been shaped by numerous socio-economic and political factors including the dichotomy between a nationalised Indian energy sector (upstream and downstream) and a more ‘liberated’ economy; centre-state relations; a rising

Low-Income Households Need to Be Part of the Clean Energy Revolution

Nearly a third of U.S. households struggle to afford their energy bills, with one in five cutting back on or forgoing necessities such as food or medicine to pay for electricity and heat, according to the U.S. Energy Information Administration. Some 14 percent have received a disconnection notice, and 10 percent keep temperatures at unsafe

Integrated approach could help to end energy poverty

With almost four years completed since the United Nations adopted the 2030 Sustainable Development Goals (SDGs), we face a narrowing window of opportunity to mobilize the disruptive solutions and ambitious partnerships needed to bend the curve and improve the lives of billions within that timeframe, or indeed sooner. Nowhere is a sense of urgency greater

New battery to store clean energy

Researchers have built a more efficient, more reliable potassium-oxygen battery, a step toward a potential solution for energy storage on the nation's power grid and longer-lasting batteries in cell phones and laptops. In a study published Friday in the journal Batteries and Supercaps, researchers from The Ohio State University detailed their findings centering around the

Breaking cycle of poverty could start in preschool

New research from one of the country’s leading experts in childhood development shows high-quality educational interventions in a child’s first few years of life can result in lasting economic, health and social benefits that extend beyond a single generation. In 2010, James Heckman, a Nobel Laureate with the University of Chicago’s Center for the Economics

Cut emissions and poverty, not trees,..

LONDON (Thomson Reuters Foundation) - Giving local communities the responsibility to manage forests - which are shrinking worldwide - could help ease poverty and deforestation, scientists said on Monday in what they described as one of the largest studies of its kind. Researchers examined more than 18,000 community-led forest initiatives in Nepal, using satellite images

LED bulbs often cost more in poor neighborhoods

In many low-income neighborhoods, upgrading to energy-efficient lightbulbs costs more than twice what it does in higher-income areas. Tony Reames of the University of Michigan led a research team that surveyed 130 stores across Wayne County, which includes Detroit. Reames: “Fewer stores in higher poverty areas even carried LED bulbs, but when they did, they

Why off-grid blooms in middle-income countries

Two hypotheses are natural starting points to address the question around pockets of growth. Firstly, off-grid will be attractive where there is strong demand for electricity. If off-grid electricity responds to energy poverty, then it can be expected that countries with lower electrification rates will be fertile grounds for these technologies. A second explanation could

AI is on its way to becoming the brain of the grid

In May 2017, Bill Gates wrote an open letter to college graduates offering some career advice. In it, he said if he was starting out today, he’d consider entering one of these three fields: artificial intelligence, energy or bioscience. On artificial intelligence (AI), he said, “We have only begun to tap into all the ways

‘The future of life on Earth lies in the balance’

Almost 600 conservation experts have signed the Call4Nature open letter written by wildlife charity WWF, which is being published to coincide with the IPBES report (see letter below).

Crowd Oil – Fuels From Air-conditioning Systems

Researchers at the Karlsruhe Institute of Technology (KIT) and the University of Toronto have proposed a method enabling air conditioning and ventilation systems to produce synthetic fuels from carbon dioxide (CO2) and water from the ambient air. Compact plants are to separate CO2 from the ambient air directly in buildings and produce synthetic hydrocarbons which

What happens when schools go solar?

Sunshine splashing onto school rooftops and campuses across the country is an undertapped resource that could help shrink electricity bills, new research suggests. The study, published in the April issue of the peer-reviewed journal Environmental Research Letters, shows taking advantage of all viable space for solar panels could allow schools to meet up to 75

Solar power: India calls for concerted efforts to ensure energy

Dubai: India has called for concerted efforts across Asia to ensure energy security in the region for sustainable development and poverty eradication by pursuing non-polluting renewable sources such as solar power. Speaking at the 16th Ministerial Meeting of Asia Cooperation Dialogue (ACD) in Doha, Qatar, Minister of State for External Affairs V K Singh urged

Renewable energy to outpace coal for first time ever in US

Another tipping point in energy seems to be on the horizon, as renewable energy in the US is expected to surpass coal in electricity generation for the first time this month. Renewables (including hydro, solar, wind, biomass, and geothermal) are projected to generate more electricity than coal-fired plants in April, according to the Institute for

10 ways to accelerate progress against climate change

Climate scientists told us late last year in the National Climate Assessment that the United States is already experiencing severe and costly impacts of a changing climate. In a separate United Nations report released in October, scientists reported that limiting global warming to 1.5 degrees Celsius would require a gargantuan global effort — and that we have roughly 12 years to
