President Trump accused climate change scientists of having a "political agenda", telling Fox News he was unconvinced that humans were responsible for the earth's rising temperatures

You should really study how global warming works.  Here, let me help:  It's like when a Russian whore pisses on Trump's head.  It starts out really warm, maybe even hot - but as it "trickles" down his head, face and body, it cools, until it's just a puddle of cold urine on the mattress.  I hope that helps......

Report: U.S. Led All Countries in Reducing CO2 Emissions in 2019

Here's what the IEA had to say about the science of the U.S. reduction in carbon emissions:

...a fall of 140 Mt, or 2.9%, to 4.8 Gt. US emissions are now down almost 1 Gt from their peak in the year 2000, the largest absolute decline by any country over that period. A 15% reduction in the use of coal for power generation underpinned the decline in overall US emissions in 2019. Coal-fired power plants faced even stronger competition from natural gas-fired generation, with benchmark gas prices an average of 45% lower than 2018 levels. As a result, gas increased its share in electricity generation to a record high of 37%. 

In his November 4, 2019 statement "On the U.S. Withdrawal from the Paris Agreement," Secretary of State Mike Pompeo spoke about the "unfair economic burden imposed on American workers, businesses, and taxpayers by U.S. pledges made under the Agreement."

Essentially, Pompeo is saying that Americans shouldn't have to pay for the environmental shortcomings of other nations.

Electricity in the U.S. - U.S. Energy Information Administration (EIA)

WWW.EIA.GOV

---

The major fuel/energy sources and their contribution to annual U.S. electricity generation.

 

Fossil fuels are the largest sources of energy for electricity generation

Natural gas was the largest source—about 35%—of U.S. electricity generation in 2018. Natural gas is used in steam turbines and gas turbines to generate electricity.

Coal was the second-largest energy source for U.S. electricity generation in 2018—about 27%. Nearly all coal-fired power plants use steam turbines. A few coal-fired power plants convert coal to a gas for use in a gas turbine to generate electricity.

Petroleum was the source of less than 1% of U.S. electricity generation in 2018. Residual fuel oil and petroleum coke are used in steam turbines. Distillate—or diesel—fuel oil is used in diesel-engine generators.

Crescent Dunes: Another Obama Solar Failure

The Nevada solar-energy plant Crescent Dunes has gone under after receiving a $737 million federal loan guarantee during the Obama Administration. Crescent Dunes, a 110-megawatt facility, was supposed to use molten salt to store heat from the sun, produce steam, and generate electricity even when the sun was not shining. The Department of Energy finalized its loan guarantee on Sept. 23, 2011—a week before the federal loan program expired. Just prior to the finalization of the loan guarantee, Nevada approved $119.3 million in tax abatements for Crescent Dunes over 20 years. The plant also received roughly $140 million in private investment. NV Energy, the largest electric utility in Nevada, agreed to buy the electricity under a 25-year power purchase agreement. Crescent Dunes began commercial operation in November 2015, missing the deadline established by its agreement with NV Energy. But, less than a year later, the facility went offline because of a massive leak in the hot salt tank. Crescent Dunes resumed operations in the latter half of 2017, but had frequent and prolonged outages.  

In the summer of 2019, Crescent Dunes’ hot salt tanks had a catastrophic failure, causing ground contamination and requiring the removal of the solar tower that is needed for the plant to generate electricity as designed, halting operations. The Department of Energy sent a formal default notice in September, followed by NV Energy terminating its power purchase agreement.

Crescent Dunes was not cost-effective. Its average price was over $132 per megawatt-hour.

In September 2011, the Energy Department indicated that Crescent Dunes would be the first of its kind in the United States and the tallest molten salt tower in the world based on Solar Two, a 10-megawatt test facility in the Mojave Desert decommissioned in 1999 that had shown it was technically feasible to use molten salt to store and generate power. However, in a 2006 report, the Energy Department said the pilot plant was never expected to be a viable commercial-scale plant and, in fact, did not validate economic feasibility. The Crescent Dunes project shows that government investments under the Obama Administration were based on politics more than feasibility. Like Solyndra, Abengoa,  Crescent Dunes is another Obama Administration failure in solar energy development. Despite Crescent Dunes’ power being priced over 4 times as high as the nearest photovoltaic plant in Nevada, the Obama Administration chose to invest in it with taxpayers’ money to further its development of renewable technology. It is well known that the government has a poor track record for picking winners and losers, and Solyndra and Crescent Dunes are notable examples. Americans should be cautious about government attempts to pursue technology in the name of climate change, a recipe for many more Crescent Dunes fiascoes.
