Energy production is one of the biggest threats to the environment. If you make your energy greener and leaner, you lessen the burden on the environment. And that's exacly what California has done. Treating the cause, not the symptoms.baha wrote:I told you before. Our biggest problem is not energy, it's the environment. You are treating the symptoms, not the cause.
California’s Energy Efficiency Success Story: Saving Billions of Dollars and Curbing Tons of PollutionCalifornia’s long, bipartisan history of promoting energy efficiency—America‘s cheapest and cleanest energy resource—has saved Golden State residents more than $65 billion, helped lower their residential electricity bills to 25 percent below the national average, and contributed to the state’s continuing leadership in creating green jobs. These achievements have helped California avoid at least 30 power plants and as much climate-warming carbon pollution as is spewed from 5 million cars annually. This sustained commitment has made California a nationally recognized leader in reducing energy consumption and improving its residents’ quality of life. California’s success story demonstrates that efficiency policies work and could be duplicated elsewhere, saving billions of dollars and curbing tons of pollution.
California Greenhouse Gas Emissions for 2000 to 2016California’s GHG emissions continue to decrease, a trend observed since 2007. The largest reductions came from the electricity sector which continues to see decreases as a result of the state’s climate policies, which led to growth in wind generation and solar power, including growth in both rooftop and large solar array generation. During the 2000 to 2016 period, per capita GHG emissions in California have continued to drop from a peak in 2001 of 14.0 tonnes per person to 10.8 tonnes per person in 2016, a 23% decrease. Overall trends in the inventory also demonstrate that the carbon intensity of California’s economy (the amount of carbon pollution per million dollars of gross domestic product (GDP)) is declining, representing a 38% decline since the 2001 peak, while the state’s GDP has grown 41% during this period.

I told you before. Our biggest problem is not energy, it's the environment. You are treating the symptoms, not the cause. It makes me think of a bunch of ants swarming around after Mother Nature kicked a hole in your anthill. You can build it back but she will just kick it again, harder.
Show me a plan where the usage in CA is lowered at the same time as the superconducting DC grid connection to NV is built. While you are refilling Lake Mead thru conservation upstream (shutting down irrigated farms) and building your pumping stations and desalination plants.
There is no plan. You are putting bandaids on the problem. You need surgery

This one?
The result: power prices are slipping to zero or even below more often in more jurisdictions. That’s adding to headaches for generators from NRG Energy Inc. in California to RWE AG in Germany and Origin Energy Ltd. in Australia. Once confined to a curiosity for a few hours over windy Christmas holidays, sub-zero cost of electricity is becoming a reality for hundreds of hours in many markets, upending the economics of the business in the process.
During the 1950s, TVA experimented with the idea of "pumped storage" at Hiwassee Dam. There it employed an energy-generating turbine that was run in reverse during low-demand hours to pump water below the dam into the upper reservoir. This integration of pump and turbine was the first of its kind in the United States; further, at the time it was the largest and most powerful in the world. The unit was built by Allis-Chalmers Company. The "pump-turbine" at Hiwassee is designated a "National Historic Mechanical Engineering Landmark" by the American Society of Mechanical Engineers (ASME).
Hiwassee Dam’s Unit 2 Pumps It Up
After five years of inactivity, Hiwassee Dam’s groundbreaking Unit 2 reversible generator/turbine unit is fully back in action, allowing TVA even greater flexibility to generate electricity—or remove it from the grid when needed to help balance base load.
JULY 7, 2016—In 1952, TVA conducted an experiment at Hiwassee Dam, designing a reverse-drive generator/turbine there—Unit 2—that could pump water from below the dam up into the reservoir above it. The dual function could generate 85 megawatts of electricity when acting as a turbine, or in pump mode could take electricity off the grid when demand for power dropped quickly.
It was the first of its kind in the United States, and at the time the largest and most powerful in the world. So important was Hiwassee Unit 2 that it was designated a National Historical Mechanical Engineering Landmark by the American Society of Mechanical Engineers in 1981.
But you haven’t heard much about it—especially lately. That’s because Unit 2 has been in hibernation. When the unit’s breakers experienced a failure on July 5, 2011, TVA chose not to restore its pumping abilities. The unit could still generate power through traditional hydro generation means—but the reversibility was no longer possible.
“The decision came this year to restore its pump capability because hydro provides flexibility in meeting demands,” explains Michael Richards, plant group manager. “With Watts Bar Unit 2 coming on with its large base load, it was a good time to return this unit to service.”
Kenny Mullinax, vice president, Western Coal and Hydro Generation, affirms Hiwassee Unit 2’s renewed importance. “With system turndown becoming more important with the addition of a large base load unit to the portfolio, having additional pumping capabilities is extremely important,” he says. “It is of significant help to the balancing authority to regulate the grid.”
The project was coordinated across TVA teams, and came in ahead of schedule and under budget, according to construction manager Brenda Byers. Repairs began April 17 and ended June 15, at a cost of $1.3 million.
The restoration project included not only repair of the breakers but included replacing a transformer, exciter, exciter transformer and repairing the wicket gate brakes.
Hiwassee Dam in North Carolina was a TVA construction project that began in 1936, one of 16 dams it built in that period. Unit 1 went online in 1940 and is strictly a generator, without pumping capability. Raccoon Mountain is also a pumped storage site, with four units with a capability of pumping 1,500 MW. It came online in 1978.
