Comments Off on Denmark to end subsidies for renewables much sooner than anyone thought possible

The renewable energy industry is performing extremely well in Denmark . The country’s energy minister Lars Christian Lilleholt said it’s performing so well, they’ll be able to stop providing state support for clean energy providers in just a few years. Denmark’s renewable energy industry will be able to stand on its own, and Lilleholt said he could not have predicted this outcome even last year. Denmark’s renewable energy industry needed subsidies for over 40 years. But soon they’ll be able to survive without a boost from the government. According to Lilleholt, the country’s experience shows it’s no longer cheaper to produce coal than renewables. The milestone is even more crucial right as the direction of global energy policies is uncertain while United States President Donald Trump embarks on an ill-advised attempt to revive coal . According to Bloomberg, the president has “made clear he’s an enemy of wind power .” Related: Denmark just broke its own wind power record for the second year in a row Lilleholt said technology will help clean energy become even more efficient and said “already today, it’s impossible to build a new coal power plant without support.” A government-appointed panel gave him the findings on the energy future of Denmark, and said the country is set to meet power needs entirely with renewable energy by 2050. Half the country’s energy requirement could be supplied by renewables as soon as 2030. The panel thinks a large amount of new capacity will be constructed without subsidies. Industry members seem just as surprised as Lilleholt. Outgoing CEO of engineering firm Danfoss Niels B. Christiansen thinks the price of producing renewable energy could fall below market electricity prices between 2020 and 2030, saying, “A year ago, it was debatable whether renewable energy costs could drop so low. But everyone’s now thinking that it will probably happen sooner.” Denmark is home to both the world’s largest wind turbine manufacturer and world’s largest offshore wind farm operator, Vestas Wind Systems A/S and Dong Energy A/S .

Scientists create super-strong bricks from mars-like soil

Comments Off on Scientists create super-strong bricks from mars-like soil

Future Mars dwellers may actually be able to use locally-sourced materials for their buildings. Four University of California, San Diego engineers were able to press Mars-like dirt into bricks in a study funded by NASA . No other materials were necessary to keep the blocks together. And the bricks were incredibly tough – even more than steel-reinforced concrete . A high-pressure hammer helped the engineers pack dirt – with the same chemical composition and grain size and shape as soil on Mars – into strong bricks. Since storage will be limited on any craft carrying astronauts to Mars, they may be able to devote room to other equipment if they know they can construct habitats with the red planet’s resources. Related: Scientists use Martian dust to 3D print tools On Earth we typically have to employ some type of adhesive to keep construction materials together. But simulated Mars dirt actually has a chemical ingredient that helps bind it. Structural engineer Yu Qiao told The Verge the chemical ingredient “gives the soil strength when it’s compacted.” It may be feasible for humans to hammer out bricks on the red planet as well. NASA life sciences expert Jon Rask, not part of the study, told The Verge, “It’s really easy to swing a hammer on Mars. You can imagine a Mars explorer swinging a hammer to make strong building blocks.” The team worked with lunar soil in the past, when NASA aimed to go back to the moon . Lunar dirt requires a binder, but since the binder would have to be shipped from Earth, the team worked with the lunar dirt until they were able to take the binder content below the 15 percent construction materials on Earth generally require to just three percent. When NASA shifted its focus to Mars, the team did too, and decided to test their lunar dirt findings on Mars dirt. They first tried packing the dirt into blocks with six percent binder, and when that worked well, they decided to test the Martian dirt further and discovered it necessitated no binder whatsoever. The journal Scientific Reports published the engineers’ findings online yesterday. Via The Verge Images via the University of California, San Diego

Comments Off on Solar and Wind Energy are Finally Cheaper than Fossil Fuels in the United States

Solar and wind energy have long struggled to compete with conventional energy sources on two fronts: dispatch and cost. However, new U.S. industry data outlined in the New York Times reveals the cost of these renewable energy sources has fallen dramatically in the last five years, making them competitive with — and sometimes even undercutting — fossil fuel-sourced energy.

Comments Off on Group Aims to Land a Robotic Probe On the Moon in 10 Years with Help from Kickstarter

The Rosetta/Philae probe landing on a comet last week has reignited in earthlings a passion for space exploration. But now that NASA’s shuttle fleet is grounded and most spacecrafts belong to private companies, there is no group that is really pushing the envelope in terms of being space pioneers. That has not stopped one small group of Brits who have decided they are going to fund their own moon mission via Kickstarter .
