It actually takes less energy and produces less carbon dioxide to cool a home in Florida then it does to heat a home in Minnesota in the winter -- especially if the home is heated by oil or electricity.
Now some creepy news from Ukraine ...
That's a lot of crude oil they are moving around the state ...
An interesting history of solar power, as it's been developed over the past 50 years.
Not surprising, but its a good reminder of the riks.
Thank god for the freon replacements ...
A common belief is that solar panels became cheap because of low-cost Chinese labor and lax Chinese regulation. This article argues that it's mostly an issue of scale of production.
Think positive thoughts.
This is pretty neat.
The climate is a changing ...
Renewable energy is a lot like agriculture. There are millions of farms across the country, each producing a small portion of the commodity over vast tracts of land. Farms and warehouses store commodities like silage and corn for long-periods of time, allowing off-season access to seasonal produce to feed animals and humans alike year round. The agricultural system is quite cost-effective at producing food at affordable prices for most Americans. There is no reason we couldn't have millions of solar cells and wind turbines across America.
Electricity is very difficult to store in quantity. But so is food and feed. Both food and feed rot if left out to elements, and many foods can't even be stored for long periods of times even with the best of technologies. That's why a lot of foods are imported from other parts of the country out-of-season or other parts of the world where it's in season. But there is no reason we can't move electricity around long distances, nor is there any reason why we can have ample storage of electricity in many diversified storage facilities -- from big pump-hydro to batteries and flywheels.
A lot of people have been talking about the Cooperstown Holsteins Court of Appeals oral arguments today.
From the article:
"Half way through Cooperstown Holsteins’ five-year mineral rights lease, mining — and in particular hydrofracking — became a hot topic. Local residents opposed to fracking have taken up strong opposition to anyone leasing their mineral rights."
"Ironically, the land Cooperstown Holsteins has leased is unsuitable for fracking because the layer of Marcellus shale is too shallow to drill. The next layer is sandstone, which could support conventional drilling, something that has been done for the past 60 years without incident in western New York state. Below the sandstone is the Utica shale, which is unproven."
