World Water Day 2021 in Review

 World Water Day 2021 (in the rear-view mirror): Valuing Water.

World Water Day (March 22, 2021) is past (www.WorldWaterDay.org)...   By now you should have taken the Water Day Quiz at SustainZine. It’s been about 10 years since I developed such a quiz. I had to work to improve and update the original quiz… It is still tricky to get good answers to some of these water-critical issues. Often the water usage is available to the homeowner, but gets confusing as the data is aggregated for the state and for the nation. The more abstract uses of water, like virtual water, are erratic and imprecise. Important concepts, but the answers are fuzzy.

Sustainability in EDU Over last 20 years

The SustainZine has been blogging (although rather sporadically) for 11 years. Wow!. One of the first blogs was related to an article (and a SAM presentation) by Hall, Tayler, Zapalski and Hall (2009). It focused on sustainability in Higher ED, specifically on how the facilities of universities were doing sustainability initiatives but there were few actual classes on Sustainability. The classroom, i.e., the future of sustainability was far behind.

Later in 2010 Hall (2010) published an article on Lessons of recessions: Sustainability education and jobs may be the answer. (SustainZine Blog post here.) This article discusses the Great Recession of 2007-2008. Make no doubt about the pandemic of 2020, it too was a recession so destructive innovation has been (and will continue to be) the result.

Renewable Investment Tax Credit (ITC) is Extended Two Years


Good news, as of January 2021 the ITC has been extended at 26% for 2021 and 2022. See Solar Energy Industry Association (SEIA) discussion on the investment tax credit (ITC) here: Solar ITC Rate Per Year

This means that the calculator we developed for residential and for business solar investments will still be accurate for the next two years. (See our Solar Profit Calculator page.)

Woo Hoo! Happy Days!:-)

During that time Biden administration should start to remove the fossil fuel subsidies, meaning that renewables should continue to take share from coal, oil and gas. There's two other things that Biden will likely do: extend renewable incentives; and, institute a cost structure for carbon. Only the renewed incentives was likely before the US Senate went 50+1 for the Democrats. Something like a gas tax increase or a cap-and-trade program was highly unlikely just a month ago.

Solar Prices Dropped off a Cliff and Into the Ocean

Here's a great article in Clean Technica by   on the falling prices of solar (PV). The cost per watt is the key measure to follow. Basically a rule of thumb is that $3 per Watt installed should be profitable, before any tax credit considerations. In 2006 the cost was $3.50 per watt for the panels. Now prices have dropped below $0.50 and would be lower if there wasn't a trade tiff going on with China.  Even with $1 to $2 per watt installed, the prices are getting to be crazy low. The Investment Tax Credit dropped to 26% percent in 2020 and will drop to 22% in 2021, but the installed costs after tax benefits should be less than $2 per watt. That's a crazy profitable investment, especially for businesses. (See our discussion and  Solar Calculator on the residential and business PV investments.)

Mysteries of Methane Leak in Florida and Not-So-Clean Fossil Fuels

There’s a BIG NatGas leak (Methane) in Florida. The source of which is not being owned up to. There’s no oil/gas drilling in the area. And, until about a year ago, most such leaks might go totally unnoticed. Read the Bloomberg article No One is Owning Up to Releasing Cloud of Methane in Florida.
Oil Flaring at Night in North America (Bakken)

First Methane. The largest component of natural gas (NatGas) is methane (EIA). Various oil formations of fossil fuels are oil, mostly gas, or a combination. Even in coal formations there is methane, which has made coal mining especially dangerous for explosions and fires.
When you see the flame stacks burning above oil wells and refineries, this is natural gas being flared off. Flaring is far preferred then just releasing it, venting, because methane is a wicked greenhouse gas (GHG) at 82 times the global warming capacity as CO2 in the first 20 years (about 30 times as potent over 100 years).
