Life After Coal

Coal- it’s the original fossil fuel. Its concentrated energy powered the Industrial Revolution, and raised humankind’s standard of living to heights that had never been possible.

But now that coal has been thoroughly supplanted by natural gas, which may soon itself be replaced by renewables, how can we restore mining communities, provide stable, high-paying jobs and an identity for former coal communities that they can be proud of? The answer may come from Germany, a country with a lot of former coal mines and ambitious renewable energy goals.

In the northwest region of the country, two professors at the University of Essen-Duisberg began to brainstorm possible uses for the old mines- the last of which will cease operations next year- and have come up with an intriguing concept: repurpose the old mines as battery storage for the wind turbines that are quickly replacing the mines in German coal country.

Not Your Dad’s Solar: Solar Balloons Could Produce Electricity 24 Hours A Day

solarcloudsEveryone knows that renewable energy is winning the race to produce the electricity of the future, some people still have doubts about their ability to handle all our current energy needs, particularly because of the intermittent nature of wind and sun.

Now a team of researchers at NextPV may have figured out a way to get around that little problem.

Teachers! Check Out the New Green Design Lab Website

gdl_blogThe Solar One Education team is excited to launch our new, enhanced website, thegreendesignlab.org!

The new website is easy to navigate and offers new features for registering for our Professional Development Workshops, the Green Design Lab Energy Challenge, and a host of resources for our Sustainable Schools Network members!

Since its inception 6 years ago, the Green Design Lab has grown to reach teachers and students in over 400 schools. During this time, Solar One Educators have provided professional development training for teachers on our hands-on curriculum, in-class programming for students, and support for energy reduction and school sustainability projects. With the development and growth of the Green Design Lab Sustainable Schools Network (SSN), Solar One Educators have reached teachers across the United States.

NYC Selects Envision Solar Mobile EV Charging Stations

evchargingnycDid you know that NYC is projected to become one of the leaders in electric vehicle use? Well we are, and the city is preparing by offering an Invitation to Bid to Envision Solar’s EV ARC solar-powered EV charging stations.

While in some ways the design (pictured) seems a little clunkier than the more shed-like solar charging stations we’ve seen in the past, the fact that these stations can be moved around the site where they are located seems like a big plus.

So when will these stations be installed, and where?

Do Oil Prices Affect Electricity Prices in the US? Apparently Not, Despite What Investors Think

pvpowerplantInvestors are freaking out a bit over the price of crude oil, which has dropped precipitously since June 2014. But they’re not just freaking out over their fossil fuel stocks- they’re freaking out about solar investment as well. Over the last six months, the stock prices of publicly traded solar companies has fallen sharply, to 60-70% of their initial stock prices.

But is cheap oil really as bad for solar development as the numbers indicate?

Meet the Smartbulb

smartbulbsRemember when light bulbs were simple? There was one kind (incandescent) at maybe four wattages- 25, 40, 60 and 100 were common- and sometimes you’d encounter something fancy like a 3-way bulb or maybe a colored bulb. Sure, they were inefficient and unrecyclable, but they were ubiquitous, and every grocery store, gas station and hardware store in American carried the exact same ones.

Then along came the CFL and everything changed. Incandescents were out; CFLs, halogens and fluorescents were in. Yes, they had traces of mercury in them that made them dangerous to break, and they had to go back to the store to be recycled. So LEDs were introduced. With their super-long lifespans and ultra-efficient electricity consumption, they seem to have won the game.

Enter the smartbulb.
