Andrew Conrad for PSFK: It’s no Yellow Brick Road, but residents of Olsztyn, a town along the Lyna River in northern Poland, can now follow along this glowing bike path to travel safely to their destination. Using solar power, it is said that the path can remain illuminated for up to 20 years.
The engineering breakthrough, developed by Polish firm TPA, was unveiled in late September as a 100-meter trial section with plans for expansion. The asphalt in the path is blended with particles that absorb energy from the sun during daylight hours and then glow for up to 10 hours once the sun goes down. The plan is to increase the shorter section following winter. Cont'd...
The Guardian: On a sunny October morning, our boat passes the run-down relicts of Liverpool’s maritime past and heads down the river Mersey and into the Irish Sea. As we steam offshore, I see in the distance a cluster of tall structures that soon reveal themselves to be towers of a wind turbine array. Arriving at the windfarm, six miles offshore, the turbines rise as high as 650ft, taller than the tallest church in the world. Each of the turbines’ three shiny metallic rotor blades is nearly 300ft long.
“A single rotation of an eight-megawatt turbine will cover the daily electricity consumption of an average British household,” says Benj Sykes, vice president of Dong Energy Wind Power, the company that is constructing and co-owns this wind project, as the boat rocks in five-foot swells. Cont'd...
Joshua S Hill for CleanTechnica: A new study has concluded that transitioning to wind and solar power would be a cheaper option for the United Kingdom to replace its coal fleet than using biomass electricity generation.
According to a new study published this week by the Natural Resources Defense Council (NRDC) and conducted by London-based Vivid Economics, which examined the full system costs of renewable energy technologies like wind and solar in comparison to biomass as a replacement for the UK’s coal fleet, wind and solar came out as the cheaper option.
The UK already uses a lot of biomass for electricity generation, with the report concluding that “biomass supplies the lion’s share” of the country’s renewable electricity generation. However, as the authors of the report note:
“…recent science shows that many forms of biomass produce more carbon emissions than fossil fuels like coal and natural gas—especially biomass from forests—increasing carbon pollution precisely when the United Kingdom aims to rapidly decarbonise its electricity sector.” Cont'd...
Nicholas K. Geranios for AP: Scott Brusaw has a vision for the nation's roads.
He believes the solar-powered glass pavers his company makes could transform thousands of miles of pavement into a new energy source.
His business, Solar Roadways, recently unveiled its first public installation, in a downtown plaza in this northern Idaho resort town. It's 150 square feet of hexagon-shaped solar panels that people can walk and bicycle on.
The company is working on proof that the panels, for which it has a patent, are strong enough and have enough traction to handle motor vehicles, including semitrailers.
"Our plan is to replace all the asphalt and concrete," said Brusaw, noting concrete occupies over 48,000 square miles in the U.S. "If you cover it with solar panels, we can make three times our energy needs."
Solar Roadways is among a growing number of companies embracing renewable energy as the U.S. aims to reduce carbon emissions by one-third from 2005 levels by 2030. Cont'd...
