POWER SECTOR CO2 EMISSIONS AT LOWEST LEVELS SINCE 1988

C

Canceled
The latest update to Carnegie Mellon University’s Power Sector Carbon Index (PSCI)—a quarterly report that tracks carbon dioxide (CO2) emissions and intensity from the U.S. power sector — shows that 2017 U.S. electricity generation CO2 emissions were 27 percent below 2005 levels, as the following chart from the report illustrates.

Not coincidentally, the report also shows that natural gas’ share of the total electricity generation mix increased 67 percent during that time (760 to 1,270 million megawatts), helping power plant CO2 emissions drop to their lowest levels since 1988. As the following chart from the report illustrates, natural gas’ net electricity generation share has jumped from 19 percent in 2005 to 32 percent last year, thanks largely to abundant and affordable natural gas supplies made possible by shale development.

Who would have thought that our ability to continually innovate new technologies, facilities, disciplines, and methods would naturally lead to improvements in emissions over time?

Who would have imagined that this was achieved largely through fracked gas and not renewables? That is the salient aspect that you've failed to acknowledge. Not just you, of course, it is a message that hardly registers amidst all the noise that comes from the media, politicians and tree huggers.

It would be a cold day in Hell before the Algorians would ever acknowledge that fact. Merciless doom and gloom is an essential part of scaring the shit out of the sheeple.

Well, naturally, I believe we're going to be stuck with fossil fuels for some time to come. How we handle it—from extraction, to refinement, to utilization—is what continues to improve in the meantime.

Cue for our old friend Kudzu to come aboard and tell us all once again that Saudis are giving it large on solar.

CCGT, nuclear and hydro are more than capable of providing all future electricity requirements. Certainly until fourth generation nuclear and fusion become available.

Yep, and we can definitely get to that point, notwithstanding all of the fear surrounding nuclear.

Why not? Solar energy is clean and non polluting.. It won't replace gasoline for automobiles..


Applications of solar energy in Saudi Arabia have been growing since 1960. A systematic major research and development work for the development of solar energy technologies was started by King Abdulaziz City for Science and Technology (KACST) in 1977.

The Saudi Solar Radiation Atlas project was initiated in 1994 as a joint research and development project between the KACST Energy Research Institute and the US National Renewable Energy Laboratory (Said et al., 2008).

The solar village project site is located 50 km northwest of Riyadh and supplied between 1 and 1.5 MWh of electric energy per day to three rural villages. It was the biggest project of its type in 1980 and cost $18 million (Sayigh et al., 1998).

I think that it is nothing short of criminal, to brutally honest, just how much money has been wasted on subsidies for wind turbines. If that money had gone into thorium reactor research instead, we would be much further ahead in rolling out 4th gen nuclear technology

Yes, we know my dear, but not everywhere has constant sun and vast deserts.

Solar works very well in the US ... in the southern states and the west.

Imagine a huge parking garage with solar panels on top???

So why does it need such huge subsidies and feed in tariffs?

On a total dollar basis, wind has received the greatest amount of federal subsidies. Solar is second. Wind and solar together get more than all other energy sources combined.

However, based on production (subsidies per kWh of electricity produced), solar energy, has gotten over ten times the subsidies of all other forms of energy sources combined, including wind (see figure).

Perhaps we don't have the will to do it on our own.


Israelis in turn responded by purchasing huge quantities of solar water heaters. By 1983, 60% of the population heated their water with the sun. A law was eventually passed requiring the installation of solar water heaters. In 2005, Spain became the second country (after Israel) to require solar water heaters.Jul 3, 2008

I am talking about PV solar, not water based systems.

Doesn't matter. This has never been the main contributor of greenhouse gas. It is politically low-hanging fruit.


But But....the largest extinction event ever wasn't caused by an asteroid, a volcano, or a Pissy Housewife wanting an SUV so she could feel powerful. It was caused by a single-cell microbe.

Solar Water Heating | Hawaiian Electric

https://www.hawaiianelectric.com/clean-energy-hawaii/going-solar/solar-water-heating

Heating water is one of the biggest uses of electricity for many households in Hawaii. Installing a solar water heating system is a smart first step that could reduce your monthly electric usage by up to one-third.

That is not big over here. There is one house in the next street from me that has it. The vast majority of solar systems are PV based, due to the generous feed-in tariffs. Also many houses no longer has hot water tanks, instead they are fitted with gas combined and/or condensing boilers. They are fed off mains water and hence hot water is instant.

South Carolina is using more and more rooftop solar application these days.

Also, look at Portugal.. last month they produced 100% of all power needs with solar.

Germany is aiming for 80% renewables.
