7 Tips for Operating Your Mini-Split Heat Pump in the Summer

“If you own a mini-split heat pump system, you probably already know about the benefits of efficient heating and cooling, zone temperature control, and quiet operation. Mini-splits require little maintenance and are easy to operate. To get the most out of your mini-split heat pump system, check out these seven tips to maximize it’s efficiency, lower energy costs, and enhance your comfort during the summer months.

 

Choose your comfort level.
Don’t get hung up on the number. When choosing the temperature setting on the remote for your mini-splits, you may discover you need to set it higher or lower than you would expect. Part of this is due to the fact that the temperature is measured at the level of the indoor air handler unit, which is typically 7-8 feet off the ground. Find a setting your most comfortable with and stick with that.

 

Let your system run continuously.
Set it and forget it. A mini-split system uses less energy and keeps temperatures most consistent when it runs continuously, as in, 24/7. You also don’t need to turn the units on and off or adjust temperature settings when you’re away like you might with a central heating and cooling system controlled with a thermostat.”

GM to Curb Economic Ties With Trump: Live Business Updates – GM Quits Trump lawsuit against CA

“Over the past four years, General Motors has emerged as one of President Trump’s favorite corporate targets. He attacked the company repeatedly for closing a plant in Ohio and lashed out at it even when the automaker offered to make ventilators this spring in response to the coronavirus pandemic.

And Mr. Trump ridiculed the company’s chief executive, Mary T. Barra, one of the few women to lead a large U.S. corporation. “Always a mess with Mary B,” he wrote on Twitter in March.

The company and Ms. Barra have not responded to the presidential wrath, but on Monday G.M. broke ranks with the White House on the one major issue where they were aligned. The automaker said it would no longer back the Trump administration in a fight with California over clean-air standards.

California has sought tougher standards on tailpipe emissions to battle climate change. The Trump administration loosened Obama-era standards and revoked the authority of California and other states to set their own rules, which led to a lawsuit from several states. G.M., Toyota Motor and Fiat Chrysler intervened in the lawsuit on behalf of the administration. A few other automakers, including Ford Motor, BMW and Volkswagen, sided with California.

G.M.’s support for the Trump administration surprised many auto experts given the president’s repeated attacks on the company and Ms. Barra. It also seemed to be an odd position for G.M. to take because the automaker has outlined ambitious plans to add nearly two dozen electric models to its lineup.

In a letter to the leaders of some of the nation’s largest environmental groups on Monday, Ms. Barra indicated G.M. was now backing President-elect Joseph R. Biden Jr. in his plan to cut emissions and support the use of electric vehicles.”

“As Americans suffer through immense wildfires, rising coastal flooding and an epic hurricane season, the nation’s corporations want you to believe they are coming to grips with the climate crisis.

Among the companies pledging bold emissions cuts are those that generate America’s electricity, which emit more than a quarter of the nation’s global-warming pollution. Yet, that same industry is about to make a strategic error that could render meeting its own goals far more expensive, if not impossible.

As they shut down costly and dirty coal-burning power plants, the electrical companies are planning to build 235 gas-fired power stations across the country, according to our analysis of figures compiled from commercial databases by the Sierra Club. The companies claim these are needed to replace the coal plants, and to balance fluctuations in electricity generation from rising levels of wind and solar power. This investment in new gas plants would exceed $100 billion.

If the plants are built, along with the pipelines to support them, they are likely to run for 30 or 40 years — long past the point that emissions from the electrical grid need to approach zero if we are to have a reasonable climate future.”

California Is Trying to Jump-Start the Hydrogen Economy – The New York Times

“IRVINE, Calif. — Since President George W. Bush fueled a minivan with hydrogen 15 years ago, the promise of cars and trucks powered by the fuel has come up mostly empty.

That hydrogen pump, in Washington, closed long ago. But in California, the beginnings of a hydrogen economy may finally be dawning after many fits and starts.

Dozens of hydrogen buses are lumbering down city streets, while more and larger fueling stations are appearing from San Diego to San Francisco, financed by the state and federal governments. With the costs of producing and shipping hydrogen coming down, California is setting ambitious goals to phase out vehicles that run on fossil fuels in favor of batteries and hydrogen. Large auto and energy companies like Toyota Motor and Royal Dutch Shell have committed to supplying more cars and fueling stations.

“In past cycles, there was always something missing,” said Matthew Blieske, Shell’s global hydrogen product manager. “There was a policy missing, or the technology wasn’t quite ready, or people were not so serious about decarbonization. We don’t see those barriers anymore.” “

How Does Your State Make Electricity? – The New York Times

Overall, fossil fuels still dominate electricity generation in the United States. But the shift from coal to natural gas has helped to lower carbon dioxide emissions and other pollution. Last year, coal was the main source of electricity generation for 18 states, down from 32 states in 2001.

How PG&E Overlooked Wildfire Risks in Favor of Its Bottom Line – The New York Times

By IVAN PENN, PETER EAVIS and JAMES GLANZ MARCH 18, 2019

“Tower 27/222 looms almost 100 feet tall in the Sierra Nevada foothills, a hunk of steel that has endured through 18 United States presidents. The transmission lines that it supports keep electricity flowing to much of California.

On the morning of Nov. 8, a live wire broke free of its grip. A power failure occurred on the line, affecting a single customer. But 15 minutes later, a fire was observed nearby. Within hours, flames engulfed the region, ultimately killing 85 and destroying the town of Paradise.

The equipment belonged to the state’s biggest utility, Pacific Gas and Electric. To the company’s critics, the tower and its vulnerability reflect a broken safety culture.

Five of the 10 most destructive fires in California since 2015 have been linked to PG&E’s electrical network. Regulators have found that in many fires, PG&E violated state law or could have done more to make its equipment safer.

Long before the failure suspected in the Paradise fire, a company email had noted that some of PG&E’s structures in the area, known for fierce winds, were at risk of collapse. It reported corrosion of one tower so severe that it endangered crews trying to repair the tower. The company’s own guidelines put Tower 27/222 a quarter-century beyond its useful life — but the tower remained.”

Buying Your First Home EV Charger | PluginCars.com

“It may surprise EV newbies to learn that an electric car’s charger is found on board the vehicle. It’s the equipment buried in the guts of the car that takes an AC source of juice from your house, and converts it to DC—so your car’s battery pack can be charged.

This fact doesn’t stop nearly everybody from calling the wall-mounted box that supplies 240 volts of electricity a “charger.” Actually, that box, cord, and plug has a technical name—Electric Vehicle Service Equipment or EVSE—and if you have an EV, you’re going to want to install one at home.

So, it’s slightly misleading to say we’re providing guidance about chargers because we’re really talking about buying an EVSE—which is essentially no more than an electrical device allowing drivers to safely connect an electric car to a 240-volt source of electricity. It’s not rocket science, and you should not overthink the selection and installation of an EVSE.That said, there are important differences between the various home chargers (uh, I mean EVSEs). And there are a few best practices to keep in mind.”

How Not to Deal With Climate Change, by  Michael Shellenberger – The New York Times

“Berkeley, Calif. — CALIFORNIA has a reputation as a leader in battling climate change, and so when Pacific Gas & Electric and environmental groups announced a plan last week to close the state’s last nuclear plant, Diablo Canyon, and replace much of the electricity it generates with power from renewable resources, the deal was widely applauded.It shouldn’t have been. If the proposal is approved by the state’s Public Utilities Commission, California’s carbon dioxide emissions will either increase or decline far less than if Diablo Canyon’s two reactors, which generated about 9 percent of the state’s electricity last year, remained in operation. If this deal goes through, California will become a model of how not to deal with climate change.

While Pacific Gas & Electric asserts Diablo Canyon would be replaced with other forms of clean, low-carbon power, nothing in the proposal would require the company to go that far. Instead, the plan, according to my organization’s calculations, would require the company only to invest in energy efficiency and renewables programs equivalent to about one-fifth of Diablo Canyon’s electricity output. Anything beyond that would be voluntary.” ”

Here is an excellent comment from nyt comments that I support.

“Agree with this article. I used to be an anti-nuke, but the climate emergency takes precedence. We should at a minimum use all the carbon-free nuclear plants now in service and probably build more, at least to get us over our emissions hump over the coming century. Maybe then, if we have a better mousetrap to provide carbon free baseload electric generation, we can shut down the nukes.

Safety concerns over nuclear plants are legitimate, but do not trump the climate crisis. I am also influenced by the fact that apparently France and Japan have been doing something with their waste smarter than we are –leaving wast at operating plants, because of opposition to Yucca Mountain or other permanent repository. Opposition to Yucca is really just an anti-nuclear strategy of going after a vulnerable point in the nuclear production cycle.

Many environmentalists are constrained by their pre-standing policy and ideological opposition to nuclear energy. A more pragmatic outlook would recognize that nuclear energy, like all carbon-free sources, need to be called to duty to combat our greenhouse gas emissions. It’s all hands on deck and there is no single solution.”

Rooftop Solar Providers Face a Cloudier Future – The New York Times

“Just two years ago, SolarCity and other rooftop solar providers were Wall Street darlings, and prospects for growth were flying high, as enthusiasm for solar power was seemingly boundless.After all, they had built a better mousetrap, allowing the masses to install environmentally minded solar power systems at little or no cost to them and to reduce their electricity bills at the same time.But in two years, the landscape has drastically shifted.Nevada recently rolled back the generous support it gave rooftop solar systems; 20 other states are rethinking their policies, as well. And despite the extension of an important federal tax credit last year, losses by rooftop solar companies have accelerated.”

Stop Wasting America’s Hydropower Potential – The New York Times

Is this true, does it make sense. I have no idea.too bad it was not open for readers to comment. That is a red flag.

“PRESIDENT OBAMA has described climate change as one of the biggest challenges facing our country and has said he is open to new ideas to address it. He can start by supporting legislation to increase the nation’s hydropower capacity, one of our vital renewable energy resources.Hydropower harnesses the force of flowing water to generate electricity. It already produces about 6 percent of the nation’s electricity and nearly half of its renewable energy, more than wind and solar combined. This is enough electricity to power 30 million homes and, according to the Department of Energy, avoids some 200 million metric tons of carbon dioxide emissions each year. That amounts to taking about 40 million cars off the road for one year.”
