Making Room For Wildlife

Protecting biodiversity is a critical challenge facing humanity.  Global vertebrate populations – from elephants to amphibians – declined by 58% from 1970 to 2012 and losses are expected to reach 67% in the next two years.  Think about it:  at least two-thirds of all vertebrate animals on earth have vanished over the lifetime of anyone fifty years old or over.

A byproduct of plastics production, dioxane is a clear, synthetic, liquid solvent that easily mixes with water.  It’s frequently used in paint strippers, dyes, and varnishes, as well as shampoos and body washes – particularly those that are sudsy.  Dioxane doesn’t really biodegrade and is widely regarded as a contaminant.

The North-Rhine Westphalia region of Germany was the crucible of that country’s industrial revolution and it still generates a third of Germany’s power, much of it using aging coal plants.   However, Germany’s national energy transition program is pushing the country away from coal and other fossil fuels and towards renewable energy sources.

At the end of last year, Southern California Edison turned on the largest lithium-ion battery storage facility in the world in Ontario, California.   It is a substation with 80 megawatt-hours of capacity, enough energy to power 2,500 households or charge 1,000 Tesla cars a day.

There are many good reasons why we should be making the transition from fossil fuel energy sources but the one that is likely to be the most persuasive is strictly economic.  It has long been said that the renewable energy future will truly arrive when installing new solar panels is cheaper than a comparable investment in coal, natural gas, or other options.

Solar Power 24/7

The biggest challenge facing both solar and wind power sources is that they don’t produce power around the clock; they only work when the sun is shining or the wind is blowing.  As a result, they don’t quite measure up to the requirement for power on demand.

Most Americans are bullish on solar power.  However, the majority of Americans are unable to install their own rooftop solar system because either they don’t own the place where they live or because their home is unsuitable for installing solar panels for one reason or another.

Electric cars are still pretty much a novelty in most places, but their numbers are increasing.  Electrical utilities around the world are trying to understand what will happen if and when there are millions of them on the road.
