John Gallagher Detroit Free Press Published 7:00 AM EST Jan 5, 2019 Gas prices have dropped below $2 a gallon for unleaded regular in Michigan and a lot of people are happy about that. But more than a few people also fret over what cheap gas means for our roads and our climate. Inexpensive fuel means more driving and thus more stress on our already-battered roads. And cheaper fuel translates into more pollution as motorists take to the roads. Maybe the marginal difference isn’t that great over the volume of traffic we see now. But with “fix the damn roads” a political mantra in Michigan and with climate change becoming an ever more urgent problem, we ought to worry about any increase in potholes and pollution. So what to do about it? One obvious idea that suggests itself is to raise the gas tax. That would immediately make gas more expensive at the pump and, according to Econ 101, would reduce the amount of driving we all do. By the way, what we call the … [Read more...] about Why cheaper gas prices could mean trouble for roads, climate

I recently posted a simple Internet meme suggesting that if we subsidized solar energy like we subsidized fossil fuels that this could be good. I posted that on Google Plus an it engendered way over 300 comments, many of which attempted to explain, often rather impolitely, that solar energy was inefficient or in some other way bad. I'm pretty sure most of those comments come to us courtesy of the bought and paid for climate change denialist campaign, funded by Big Oil to the tune of many tens of millions of dollars to date. Most of the commenters were saying similar things, most of which were either incorrect or irrelevant, and far too many of them showed up on this comment at once to be explained by normal internet behavior, at least on my Google Plus page. This was a move made by the denialists, and rest assured ... they are doing this more and more often as time goes by. What I found interesting about this is the fact that the main complaints were about how inefficient, expensive, … [Read more...] about Is Solar Energy Totally Bogus or Something that Gives Hope?
Rick Greenough, De Montfort University Sweden has built the first smart road that will allow electric vehicles to charge as they drive. The eRoadArlanda pilot scheme, which covers two kilometres of road outside Stockholm, is an attempt to solve one of the biggest challenges that the transport industry faces. Namely, how to move freight and people in a way that neither damages the climate through greenhouse gas emissions nor the quality of air through nitrogen oxide pollution. The eRoadArlanda scheme is supposed to extend the range of electric vehicles beyond what was previously possible. Yet as an engineer, I have concerns about the durability of this road. Even more significantly, the cost of the technology and the disruption that building it causes is likely to restrict any mass scale replication. If this solution cannot be widely replicated then it is really no solution at all. Instead, a serious attempt to reduce hazardous emissions should focus on more practical solutions, such … [Read more...] about What’s the environmental impact of Sweden’s new electric road?

The average American eats about 3,400 mg./day of sodium and recent studies indicate that’s just about the right amount. Regardless, the federal government continues to recommend that people eat a maximum of between 1,500 and 2,400 mg./day of sodium. Yet, there is almost no population on earth that consumes this little salt. A 2014 study, published in the New England Journal of Medicine, tested sodium consumption in more than 100,000 people in 18 countries. The study found that the healthy range for salt consumption was between 3,000 and 5,000 mg./day. The amount of salt Americans eat per day is on the low end of … [Read more...] about Are you eating too much salt, or not enough?
BRITISH Gas has come under fire as energy bills rise by £60 – the second price hike in seven months. Critics have blasted the move as a "slap in the face" for customers, who will face yet another rise in their gas and electricity bills - despite costs being lower now than they were a year ago. The increase is set to affect 4.1million British Gas customers from May 29, although they can switch to a cheaper deal to avoid it. The UK's biggest energy firm scrapped its standard tariff on March 31 and if customers do not switch they will be transferred on to a temporary tariff. It's not the first energy firm to push up costs this year, in March E.On announced that over 2 million customers on its standard tariff will see bills go up by up to £50 a year. It came on the same day that the National Grid, operator of the UK's gas pipeline network, issued a "gas deficit warning" as intense demand from households outstrips supply. How to switch suppliers and save … [Read more...] about British Gas savaged as energy bills rise by £60 – the second price hike in seven months
