New company develops ultra-low cost, long duration energy storage systems

Renewable energy technology has come a long way in the past few decades, finally making solar and wind power generation competitive with fossil fuels on price. But they don’t work when the sun isn’t shining or the wind isn’t blowing. “If we want to power the world mainly with renewables we need to find a way to overcome that variability, …

A house could be printed in a day using a novel peat material created in Estonia

Cut peat blocks were already being used for building houses thousands of years ago. Now, scientists at the University of Tartu in Estonia have developed a material which could make it possible to print energy-efficient houses out of milled peat and oil shale ash using a 3D printer. A couple of years ago, Dr Jüri Liiv invented an organic humate soil improver, …

Scientists use ‘funnel-vision’ to pioneer cheap and efficient solar energy

Scientists have developed a pioneering new technique that could unlock new methods of making solar energy more efficient. A team of experts from the University of Exeter has discovered an innovative way for generating photovoltaic (PV) energy – or ways in which to convert light into power. The new technique relies on ‘funnelling’ the sun’s energy more efficiently directly into …

Xcel Energy plans to retire two coal plants, and rely more on wind and solar

Colorado’s biggest utility company recently released details of its $2.5 billion proposal to become a cleaner power generator, retiring two coal-burning plants and by 2026 replace them with projects generating nearly 55 percent of its electricity from renewable sources. Xcel Energy (Nasdaq: XEL) submitted its plan to the Colorado Public Utilities Commission late Wednesday, laying out extensive options how it …

Little-Known Accounting Policy Could Fuel Green Infrastructure Surge

Most water agencies don’t think of local water projects like green roofs or efficiency rebates as assets, but now they can. And that means agencies can now access capital markets for funding, which could help dramatically grow these projects. IN THE YEARS to come, we’re likely to see a lot more “green” and distributed infrastructure projects from water utilities, like permeable pavement, …

Hydro, wind and solar: Undeniable synergies

“There is no technical or economic barrier to transitioning the entire world to 100 percent clean, renewable energy with a stable electric grid at low cost,” said Mark Z. Jacobson with Stanford University. This is the key finding of research completed and published in early 2018. At the heart of this study is the need to match energy supplied by …

Income Needed To Afford The Average Home Price In Every State in 2018

The housing market has not only recovered its pre-recession levels, but some observers are actually starting to worry about yet another housing bubble. Housing prices are on the rise, thanks in large part to extremely tight inventory, so it’s worth asking:  are potential home buyers getting priced out of the market? The answer depends on where they live and how …

Degrees and Concentrations in Renewable Energy Programs Grow at US Universities.

The Wall Street journal reports that American universities are increasingly offering college degree programs in renewable energy technologies to meet growing industry demand for renewable energy skills. Across the U.S., universities that have long offered degrees related to the fossil-fuels industry are starting to offer degrees and concentrations in wind and solar technologies. Companies such as Tesla Inc. are seeking …

Energy efficiency now employs 2.25 million Americans

Looking for a job or smart investment? The energy efficiency field is an increasingly good bet for workers and financiers. Here’s why: new data show it employed 2.25 million Americans last year — more than the combined total of jobs to produce coal, oil, gas, and electricity (including renewables). These data are contained in the 2018 U.S. Energy & Employment …
