Study from MIT Energy Initiative will explore the future of transportation

“Mobility of the Future” study examines how developments in technology, fuel, infrastructure, policy, and consumer preference will drive transportation changes. Emily Dahl | MIT Energy Initiative Energy demand for transportation — which today accounts for approximately one-fifth of the world’s energy consumption — is expected to rise substantially as a growing middle class in emerging […]

From teenager to pensioner—the green energy crowdfunders

Boosting the use of renewable energy has long been an ambition in Europe, but some efforts have powered down amid an ever-changing political landscape and dwindling finances. Now, crowdfunding is pulling in a new generation of green investors “I have always been interested in the environment. As a child, I thought ‘what if the world […]

Iran and Middle East could adopt fully renewable electricity systems

Iran can transition to a fully renewable electricity system and financially benefit from it by 2030. Researchers at Lappeenranta University of Technology (LUT) show that major oil-producing countries in the Middle East and North Africa (MENA) region could turn their abundant renewable energy resources into lucrative business opportunities in less than two decades. According to […]

What’s the best way for Europe to curb greenhouse emissions from cars?

As the European Union contemplates new policies aimed at meeting its emissions-reduction commitments under last year’s Paris Agreement on climate change, a new study by researchers at MIT and elsewhere could provide some valuable guidance on the most effective strategy. Rather than adopt a standard for automotive gas-mileage ratings, as the United States has done […]

Calculating the financial risks of renewable energy

For investors, deciding whether to invest money into renewable-energy projects can be difficult. The issue is volatility: Wind-powered energy production, for instance, changes annually — and even weekly or daily — which creates uncertainty and investment risks. With limited options to accurately quantify that volatility, today’s investors tend to act conservatively. An MIT spinout, EverVest, has built […]

SolarCity’s Gigafactory

                A $750 million solar facility in Buffalo will produce a gigawatt of high-efficiency solar panels per year and make the technology far more attractive to homeowners. Availability: next year by Richard Martin In an industrial park near the shore of Lake Erie, hard by the Buffalo River, the […]

Germany Runs Up Against the Limits of Renewables

At one point this month renewable energy sources briefly supplied close to 90 percent of the power on Germany’s electric grid. But that doesn’t mean the world’s fourth-largest economy is close to being run on zero-carbon electricity. In fact, Germany is giving the rest of the world a lesson in just how much can go […]

Chinese researchers develop new battery technology

A Chinese research team has developed a novel, environmentally friendly, low-cost battery that overcomes many of the problems of lithium ion batteries (LIB). The new aluminum-graphite, dual-ion battery (AGDIB) offers significantly reduced weight, volume, and fabrication cost, as well as higher energy density in comparison with conventional LIBs. AGDIB’s electrode materials are composed of environmentally […]

Solar Charging and Battery Backup For Your Home

Tesla Power Wall – Solar Powered Day and Night The average home uses more electricity in the morning and evening than during the day when solar energy is plentiful. Without a home battery, excess solar energy is often sold to the power company and purchased back in the evening. This mismatch adds demand on power plants […]
