Water and wastewater treatment plants are a place where water gets cleaned and purified and ready for drinking. Impurities such as chemicals and toxins, solids, and organisms are removed and made safe for everyone to enjoy including wildlife. So who are the people behind this operation making it all possible? These people are called Water and Wastewater Treatment Plant Operators, and the nature of their work, duties, and education is explored below. (more…)

The long term environmental benefits of converting or updating your loft have long been known. Improving the insulation capabilities of a once draughty attic means less energy is exerted when heating your home, saving both the planet and your wallet. Around 25% of all the carbon dioxide generated in the UK comes from our homes, and your loft can be one of the biggest culprits when it comes to energy waste – especially if your property is an old building that’s not been built to modern standards.

It’s always a good idea to remove chemicals from drinking water, so many of us take steps to filter those chemicals out. One of those methods is through the use of a water softener. Did you know, however, that water softeners present several dangers to you and the world around you? Here are a few ways they can negatively impact your personal health, as well as the environment.

Like my mother, a kindred spirit, I have to admit that I worry, a habit that is, to a degree, pathological. Worry doesn’t change the future; it only depresses us.  And, though 99% of the subject of our worry never happens, we do it anyway; we have no other choice; it’s the way most of us are wired.  I worry principally about my kids’ future, but also about the other things that concern those of us who try to pay attention to what’s going on in the world around us. 

Here’s something that hasn’t been around too long: the concept of “abrupt” climate change.  (more…)

Here’s a video that presents the results of the third annual Nigeria Alternative Energy Expo (NAEE 2013), held in Abuja.  Promoters say it was a terrific success; while I have no reason to doubt them, that’s what promoters say, regardless. 

I noticed that the discussion includes the circumvention of what I’m sure is extremely onerous government regulation, by keeping solar PV projects under one megawatt. It’s funny how we see the horrors of the permitting process replicated around the globe.  Apparently, Germany has streamlined the heck out of this, which is why they’re so successful in this space.

I have an old friend who sometimes gives me investment advice, and, when he feels especially confident regarding a certain item, he’ll add the warning, “If you don’t do this, Craig, you’ll be crying in your beer.”

Well, that’s certainly the way I feel about the fact that I didn’t jump into Esplanade Capital, focused on the solar PV industry.  Esplanade is run by my colleague Shawn Kravetz, who starred in our webinar on “Solar Investing” last February, and it’s up big this year.

I’m particularly impressed with Shawn’s thinking and insight in this industry.  But, truth told, the industry right now is so strong that anyone with a dartboard could have made money recently; the U.S. just posted the second-largest quarter in its history of PV installations, and main ETF (TAN Guggenheim) is up over 90%.

The energy industry is about cost-effectiveness; I think we all know that.  That’s why we’re generating electricity from coal:  it’s deadly, but it’s cheap.  Where is this all going?  I’m not sure, but I do know this: Replacements for fossil fuels, even if their costs to the environment are next to nothing, stand no chance if they are not affordable. 

Two quick points on the subject:

• The American Council on Renewable Energy (ACORE) recently published its report on the activities in this sector in the northeast region of the U.S. and presented a shockingly significant reduction in costs across the board.  Here’s an excerpt:  Three large utilities in Massachusetts, for example, recently signed long-term contracts to purchase renewable energy at less than $0.08 per kilowatt hour, below the cost of most conventional sources in the region.”

• My own work for my client Plexisun, a breakthrough in solar thermal hot water, is all about cost-reduction.  The product boasts an efficiency in the mid-teens, approximately the same as PV.  Anyone who needs hot water in any significant quantity (laundromats, dairy barns, apartment complexes, hotels, etc.) is going to love this stuff.

There you have it: two bits of good news for the adoption on renewable energy.

Before you move your home you should check out its energy performance if possible. In some ways you can do that with an energy performance certificate or its equivalent. This will give you an idea about what you need to improve around the home or your future home so you could make it more eco-friendly and possessing a smaller carbon footprint. (more…)

Tomorrow I have a phone call scheduled to talk about this fabulous investment portal: “Maximpact.com.”  I’m hoping they’ve been successful here; it certainly strikes me as a good idea, and it appears to be the perfect confluence of two hot topics: crowdfunding and impact investing.  (more…)

Here’s an article on geothermal energy that makes some good points about this resource’s characteristics as a provider of baseload power. 

It appears that there is a factual error in the article re: cost, however; the levelized cost of energy from coal is not several times less than geothermal, based largely on the fact that the latter of which enjoys zero cost of fuel (not to mention zero emissions of the burned fuel into the atmosphere).  Here are figures from the US Department of Energy and a report called “COMPARATIVE COSTS OF CALIFORNIA CENTRAL STATION ELECTRICITY GENERATION TECHNOLOGIES.”
