US Renewables Grew 10% In 1st Half Of 2017

October 5th, 2017 | by Joshua S Hill

Renewable energy sources in the United States grew by another 10% in the first half of 2017, according to new figures published by the country's Energy Information Administration and highlighted by Ken Bossong's Sun Day Campaign


Coal Pit Water Pumping Costs Set Precedent

September 17th, 2017 | by Dr. Karl-Friedrich Lenz

Today I learned that the German Ruhr region needs to find a budget of around 220 million Euro a year to deal with the environmental consequences of 150 years of coal mining. Around two thirds of that sum is needed for pumping pit water.


Pittsburgh’s Cleantech Leadership Flowering

August 24th, 2017 | by Carolyn Fortuna

Pittsburgh has committed to 50% reduction in CO2 emissions and energy and water usage by the year 2030, leading North American cities in this regard. It has made significant headway toward these goals, largely by applying lots of cleantech, according to the Pittsburgh 2030 District’s newly released 2016 Progress Report


100% Clean, Renewable Energy Is Possible, Practical, Logical — Setting The Record Straight

July 22nd, 2017 | by Karl Burkart

Since 2009, Mark Jacobson, Professor of Civil and Environmental Engineering at Stanford University and Senior Fellow at the Woods Institute for the Environment and Precourt Institute for Energy, and more than 85 coauthors have written a series of peer-reviewed journal articles evaluating the scientific, engineering, and economic potential of transitioning the world’s energy infrastructures to 100% clean, renewable wind, water, and solar (WWS) power for all purposes by 2050, namely electricity, transportation, heating, cooling, and industrial energy uses


Google Creates “Dandelion” To Promote Geothermal Energy

July 18th, 2017 | by Steve Hanley

Google has set up an independent business outside the Alphabet umbrella called Dandelion. The new company was created to promote new geothermal system technology. Dandelion will attempt to do for residential heating and cooling what SolarCity has done for rooftop solar


Cities Across USA Continue To Commit To 100% Renewable Electricity

May 6th, 2017 | by Kyle Field

Hello Solar put together an interactive map documenting all of the cities in the US that have committed to moving to 100% renewable energy*. The map includes the timing on which the cities have committed to complete the transition and the population of each for context. (Note: since the site and many cities write "100% renewable energy," we are using that language, but many of these commitments are actually just about 100% renewable energy for electricity or electricity + heating.)


Appalachia Can’t Shift From Coal To Clean Easily

February 7th, 2017 | by Michael Barnard

There will be some jobs in the region due to wind, solar and geothermal energy. It's probable that they could provide tens of thousands of jobs for workers in the region. But there are never going to be close to the 785,000 coal jobs of


Renewables = Over 50% New Electricity Capacity But 16% Of Energy Investment

January 24th, 2017 | by Zachary Shahan

Only 18% of energy investment in renewables despite >50% of new power capacity being renewables is, to me, a sign that the carbon bubble is still growing, but it's also a giant Post-it note telling investors that it's time to shift focus and put money into the future ... if they want the future to be kind to them


Renewables Now Cheapest, But How To Enable Faster Renewable Energy Growth?

January 22nd, 2017 | by Zachary Shahan

Renewable energy is now the cheapest option, on average, for new electricity capacity around the world — developed countries like the US as well as developing countries. As I noted the other day, we need to keep channeling this message to the broader public, and especially decision-makers, but there are other things to do in order to increase renewable energy growth
