Snow-on-solarHaving solar panels on your roof can allow you to sit back and enjoy decreased energy costs while being more environmentally-friendly. However, when the cold winter months roll around, it can be a time of worry as you’re unsure what to do with the mix of solar panels and snow on the roof of your home. It’s important that you take the time to properly educate yourself on the right ways to keep your roof and solar panels safe during snowstorms. (more…)

Here’s a good article for those looking for an introduction to tidal energy, though it sugar-coats the subject of costs. The author writes: “Once it’s installed in the ocean, it functions cost-competitively to other forms of renewable energy.” (more…)

22893962_2094697530541214_1057591787101037249_nRemarkably, there are still people who believe that America’s in its heyday, the swamp is being drained, that the U.S. is headed in the right direction, and that it’s well-regarded on the world stage.

The rest of us, perhaps 70% of the electorate, can’t wait for this presidential administration to be over.  We live each day hoping for more indictments.  Oh please, Bob. Please! Do it now.  Never put off for tomorrow what you can do today.  (more…)

21432786_10213148455039809_6063528944728423054_nThe 20-teens have seen the onset of a trend that will be with the developed world for a very long time to come: building infrastructure that protects our cities from the escalating ravages of climate change, as discussed in this wonderful article in the New Yorker.  There are dozens, possibly hundreds of things encompassed here, and new ones are militated with each new disaster: building sea walls and water drainage systems to prevent floods, as those resulting from Hurricane Harvey, and ensure resilient power systems to ensure that old people don’t bake to death in the heat of abandoned care facilities that lost air conditioning as they did in the wake of Hurricane Irma a few weeks later.  It’s much harder to imagine, however, how we could be capable of protecting an entire 3500 square-mile island (like Puerto Rico) in the Caribbean, where more than two-thirds of its people are still without power 38 days after Hurricane Maria.

CO2As we learned yesterday, the concentration of CO2 in the Earth’s atmosphere made a big leap from 2015 and 2016, hitting 403.3 ppm (up 3.3 from the previous year), for the first time in the last 800,000 years, according to ice core samples, at which time sea-levels were 66 feet higher than they are now.   From the article linked above: The increase essentially guarantees that in the absence of rapid and dramatic cuts to emissions, catastrophic temperature increases “well above” those the Paris agreement sought to avoid will become a reality by end of the century, according to Petteri Taalas, the head of the World Meteorological Organization.

cropped-business-1Here’s a short conversation I had about noon yesterday with a friend who manages a hedge fund, an extremely tiny portion of which is my 401(k).   The guy is a “Type A” Trump supporter (see explanation below), and, like Trump, graduated from Wharton.  I wrote this largely in jest, but he seems to have taken it seriously.

larson-cup1If you’re looking for a summary of news from the entire energy industry: fossil fuels, nuclear, renewables and all the peripheral technologies, you may want to check out Energy Matters; regular 2GreenEnergy readers will note that I quote something this source at least one a week.

From today’s edition: World energy consumption is forecast to grow by 28% between 2015 and 2040, and use of every source of energy (petroleum, natural gas, renewables and nuclear) will  increase except one: coal…..millions of people across Northern Chinese are going into their first winter heated by natural gas instead of coal.
