The U.S. needs a DC ‘super-grid’ to boost renewables and reduce pollution : TreeHugger

We could reduce CO2 emissions by 75% by 2030The United States is a single country, but it doesn’t have a single power grid. There are multiple regional grids that are not that well interconnected, making it very hard to transfer energy from one side to the other, especially over long distances since the lines are mostly alternating current (AC), which isn’t very efficient over large distances. On top of this, the AC cycles on the different grids are not synched, making it even harder to send power across…This is becoming a problem for the rise of renewable energy. Wind and solar power are intermittent sources, as is hydro, to a lesser extent. The best way to dampen that variability is to be able to share power across a very large area, sending energy from regions where there is a surplus to regions where there is a deficit, balancing things out.

GCR – Trends – France to pave 1,000km of road with solar panels

The minister told a conference of transport authorities last week that the tenders for the “Positive Energy” initiative had already been issued and the tests on the panels would begin in the spring.According to France’s Agency of Environment and Energy Management, 4m of solarised road is enough to supply one household’s electricity needs, apart from heating, and one kilometre will light a settlement with 5,000 inhabitants.So the maximum effect of the programme, if successful, could be to furnish 5 million people with electricity, or about 8% of the French population.The solarising of France’s roads involves glueing 7mm-thick strips to the surface of the carriageway. The basic technology for this has already been developed by Bouygues subsidiary Colas.The company’s Wattway panels (pictured above), which took five years to develop, were unveiled in October.

How to create a culture of early technology adoption in the workplace

Tech breakthroughs are making our lives easier — both in and out of the office.Ever-improving Apple continues to launch new versions of the iPhone. Wearable tech now employs apps to tell us what stresses us out and what makes us happy. And thanks to technology, more companies are offering telecommuting options to employees, according to a recent
SHRM study.Yet, amid all these improvements, only a meager 27% of American employees have access to the latest technology in the workplace, according to Oxford Economics’ Workforce 2020 report. Now that millennials, who grew up using new technology, are becoming decision-makers and stepping into middle management, it seems more of the workforce should have already adopted new technology.The problem might be due to difficulties convincing seasoned executives to rethink their current tools. “Our company has been doing things this way for 50 years,” millennials may hear from higher-ups.The challenge is to convince executives from different walks of life to see the value in these newfangled technologies. Ultimately, the next generation of leaders taking over the world’s top organizations need to lead the charge in adopting new technology so the workforce can benefit from innovation to the fullest extent.Here are a few approaches employees can take to lead a team of early tech adopters.
