Hydrogen has great promise in producing electricity because it has no byproduct but water. Potentially, it also has advantages over batteries as a storage medium.
That doesn’t mean we’ll be driving hydrogen fuel cell vehicles (FCVs) or storing renewable energy in fuel cells any time soon.
Pure hydrogen doesn’t exist in nature. Manufacture of hydrogen requires natural gas, biomass, alcohol, or water. The technology won’t be ready for prime time until some problems are worked out. Continue reading →
In the first quarter of 2017, the US energy storage market set a record.
The 234 MWH represents more than fifty-fold growth over the same period last year. The 71 MW capacity trails only the fourth quarters of 2015 and 2016.
Most of this growth comes from utility scale projects in Arizona, California, and Hawaii. Continue reading →
Doing recycling wrong can endanger the whole process. Including the people who work in it.
But we all make mistakes in recycling. We put materials out to the curb that don’t belong there. Or we neglect to put things in that do belong. Or we put them in the wrong way.
Recycling is a good thing, but it’s expensive. At first, it appeared that municipalities could break even by selling the material they collected. Not so any more, if ever. Commodity prices have plummeted.

So how can we recognize how we’re doing recycling wrong so we can correct our mistakes? Continue reading →
People like to do things the easy way. If we can pour something down the drain or flush it down the toilet, it just goes away. Or so we think.
But that bacon grease, chicken fat, even vegetable oil causes big problems. Any fat down the drain can clog the pipes in your house.
Unless it causes the toilet to back up or you have to call a plumber, it may seem like just a nuisance. The worst problems happen when it gets into the sewer. Continue reading →
When you use less gas, you not only save money. You use less fossil fuel.
Not only do you save what goes out your tail pipe. You save whatever fuel it would cost to refine and transport the gas you don’t use.
Some people still think green living is too expensive and inconvenient. These gas saving tips will save you money with no loss of convenience.
They come in two basic categories: how you maintain your car and how you drive. Continue reading →
Never, ever put Styrofoam in your recycling container.
It will break into tiny little pieces in the sorting equipment at your local recycling facility. Then it will get all over everything else. It will contaminate every bale of sorted recyclables.
So what should we do about it? Recycle it! Continue reading →
