Side by side the mode that fares better emissions-reduction-wise: Trains or motor transport?

Astounding it is how on a gallon of diesel a ton of railroad-hauled freight on average can be transported a distance of approximately 470 miles. Pretty remarkable stuff! Even more remarkable, substituting diesel with electric propulsion and the fuel-efficiency numbers for train-hauled freight (and passengers) look even better, and even more impressive still, when that … Read more

The climate change exchange: ‘Back-up’ plan

Whether we are talking about atmospheric normalization or global warming’s and/or climate change’s causation, “balance” is the word. That’s right, balance. So in a kind of holistic air-healing sense or maybe more precisely, a holistic air-remedying context, what does being balanced mean exactly? From physics, we know that if an object exerts a force opposite … Read more

Making tracks for high-speed freight: What’s not to like?!

There are those who rail against California’s bullet-train project asserting that the system will require subsidization. They argue that there isn’t enough available capital even to fund construction of 119 miles of line between Shafter and Madera, much less build 520 miles from San Francisco to Los Angeles and Anaheim (the complete Phase 1 portion). … Read more

Adopted rule calls for 300,000 non-polluting trucks, vans on California roads by 2035

With older, gas-fired appliance use unhealthy air in homes is oftentimes found

Natural gas. It is used to dry our clothes, cook our food, heat our water and warm our homes. All true. But, from an air quality standpoint, how clean-burning or unhealthy are the gas-fired appliances that we use? Many, apparently, just don’t make the grade. As far as unhealthy indoor air quality from natural gas-powered … Read more
