Our pathetically slow shift to clean energy, in five charts

January 10th, 2020 at 12:11 pm » Comments Off

We’d better pick up the pace in the 2020s. By most measures that matter, clean energy had a stellar decade. The cost of large wind and solar farms dropped by 70% and nearly 90%, respectively. Meanwhile, renewable-power plants around the world are producing four times more electricity than they did 10 years ago. Similarly, electric […]



Gas plants will get crushed by wind, solar by 2035, study says

November 18th, 2019 at 3:14 pm » Comments Off

Generators now on drawing boards will be left uneconomical Natural gas-fired power plants, which have crushed the economics of coal, are on the path to being undercut themselves by renewable power and big batteries, a study found. By 2035, it will be more expensive to run 90% of gas plants being proposed in the U.S. […]



Renewables meet 50% of electricity demand on Australia’s power grid for first time

November 14th, 2019 at 12:12 pm » Comments Off

For a brief moment solar, wind and hydro combined to deliver more than half the power into the National Electricity Market Australia’s main electricity grid was briefly powered by 50% renewable energy this week in a new milestone that experts say will become increasingly normal. Data on the sources of power in the National Electricity […]



How cheap must batteries get for renewables to compete with fossil fuels?

November 4th, 2019 at 1:47 pm » Comments Off

Production of lithium batteries for environmentally friendly electric cars future of energy  While solar and wind power are rapidly becoming cost-competitive with fossil fuels in areas with lots of sun and wind, they still can’t provide the 24/7 power we’ve become used to. At present, that’s not big a problem because the grid still features […]



IKEA will produce more energy than it consumes by 2020

October 2nd, 2019 at 12:44 pm » Comments Off

It hopes to be ‘climate positive’ by 2030. Many companies are pouring money into renewable energy, but how many can say they’re producing more than they need? IKEA thinks it will, at least. Its holding company Ingka revealed that IKEA will generate more renewable energy before the end of 2019 than the energy its stores […]



How hackers invented kiteboarding

September 23rd, 2019 at 12:13 pm » Comments Off

  An unusual design process combining recklessness, imagination, and computers created one of the fastest-growing sports in history. The promise of kiteboarding is that a wind strong enough to draw small whitecaps from the water can take you on a magic-carpet ride. But the same wind can be dangerously uncontrollable.Photograph from Alamy Just as he […]



Generator that creates electricity from gravity could revolutionize renewable energy

February 14th, 2019 at 1:29 pm » Comments Off

A Dutch inventor has successfully created a contraption that generates electricity from gravity – and it could revolutionize the future of renewable energy. Dutch architect Janjaap Ruijssenaars, from Universe Architecture, has developed a method to generate free energy in a sustainable way at home. The patent-pending technique, whereby energy is released by perpetually unbalancing a […]



Using molten salt to store electricity isn’t just for solar thermal plants

January 5th, 2019 at 11:38 am » Comments Off

Startup follows on a number of innovative ideas to make renewable energy more flexible. How can we make wind a more versatile energy source? By adding storage. An energy storage startup that found its footing at Alphabet’s X “moonshot” division announced last week that it will receive $26 million in funding from a group of […]



Utilities have a problem: the public wants 100% renewable energy, and quick

September 18th, 2018 at 9:06 am » Comments Off

The industry is groping for ways to talk the public down. Renewable energy is hot. It has incredible momentum, not only in terms of deployment and costs but in terms of public opinion and cultural cachet. To put it simply: Everyone loves renewable energy. It’s cleaner, it’s high-tech, it’s new jobs, it’s the future. And […]



Wind-powered Water Seer pulls 11 gallons of clean drinking water from thin air

July 21st, 2018 at 10:42 am » Comments Off

A new device that relies on simple condensation to collect clean water from the atmosphere promises to provide up to 11 gallons of safe drinking water without an external power source, greenhouse gas emissions, or adverse environmental impacts. What’s more, the innovative Water Seer collection device could potentially run forever, gifting generations of people with […]



Introducing the World’s First Large-Scale Tidal Power Farm

October 4th, 2016 at 6:29 am » Comments Off

 Scotland unveiled the first turbine for the MeyGen tidal stream project, the world’s first large-scale tidal energy farm. The project will initially install four turbines, but will eventually have 269 turbines, enough to power 175,000 homes.



A cost-effective battery that stores surplus wind and solar power a step closer to reality

October 8th, 2015 at 5:30 pm » Comments Off

A home battery that is cheap, durable, safe and as big as you like that could store solar or wind power is closer to reality. Harvard University researchers report that they have tested a “flow battery” that uses cheap and abundant chemical elements, can be operated with plastic components, will not catch fire and can […]
