Particulates are one reason most city buses in the United States now run on natural gas. That's a real improvement over diesel in terms of particulates.

The real reason to look at battery-electric buses is pure dollars and sense. Battery-electric buses can have lower lifecycle O&M costs. The current generation might not have lower O&M costs, but there is definitely a path to lower O

Thank you for this comment because it puts one of the solar cars (at least the Sono Sion) in context--10 km range per day. It's a great option if that that work for you!

What worked best for me in school was longhand notes and then nightly typing the notes up. (Though I seldom revised the notes the same night or week.) For finals I would spend a lot of time revising my notes and comparing notes with my fri

What do you mean by “emissions”? GHG emissions? Pollution emissions?

Transit does not need to lose money. Buses and trolleys used to be private and make a profit.

There are also fuel cell vehicles such as the Honda Clarity, Toyota Mirai, and Hyundai Nexo.

I also wanted to make this note about the application matters. Lithium ion are great, especially for electronics and EVs. They are pretty good for grid scale, but we need other technologies there. Currently the largest source of storage

Sadly solid state is not currently ready on a large scale. There is still significant work to be done in large part to use a solid state electrolyte.

What is the evidence for this claim? It certainly may be true, but I’d like to see evidence.

I’m not seeing the problem with plastic going into landfills. That means it doesn’t result in plastic pollution in waters and the ocean and is sequestering the carbon back in the earth.

What matters is what is being recycled. Some recycling makes economic sense today—metals for example and car batteries. The recycling of some plastics makes sense, but it has to be sorted. There is plenty of land for landfills, but for rec

Negative electricity prices are also driven by wind subsidies. Wind producers get 2.3 cents per kilowatt hour in tax credits. This means they make money even when the price of electricity is negative—-up to 2.3 cents a kilowatt hour.

The price of oil will be pretty stable over the next ten years. The life of the average vehicle is now around 12 years and getting longer. Demand for gas isn’t going to massively decrease in the next ten years. Also, many gas stations don

It is not accurate that LCOE provides apples-to-apples comparisons. For examples, there is no value for dispatchability. As EIA explains, “The direct comparison of LCOE across technologies is, therefore, often problematic and can be mislea

How has it allowed abuses? In the American west, water rights are property rights and there is clear ownership to water.

The article is talking about wastewater injection. Injecting mud while drilling isn't causing stress on faults, but rather wastewaster injection. Wastewater injection isn't drilling. That's why the title is mislabled.

This heading (and the heading of the article itself) are wrong. If you read the article it is not that "drilling" reawakens sleeping faults, but that deep injection wells do. Deep injection wells are one way to dispose of produce

True, but now is the greatest time in history to be able to pursue art. It's obviously tough, but people can sacrifice for their art and share it like never before. Just think how many incredible artists have lived but spent their enti
