I know it has been awhile since I did a residential post. I know this started out as a blog about residential energy needs and services. You know, energy efficient roofs, HVAC equipment and other such stuff. But years ago, I got off on energy related environmental stuff and then eventually Global Warming. Then anti-Nuclear stuff. Finally just raw Environmental stuff like obnoxious polluting and horrible deaths. Well today a gentleman named Chris Winters reached out and touched me so I am touching him back, so to speak. As always, I can vouch for his tips because they are somewhat general, but anything specific he is pitching I can not (For instance AC controllers – which his company sells). Also I may have put up this as an addenda to any earlier piece, so if i did forgive me.

No matter what the season, energy usage tends to increase one way or another. With long running air conditioning and increased wash cycles of sweaty laundry in summer, to high heating usage and wash cycles of bulkier laundry in winter, we simply cannot operate without electricity.

We can be extremely energy efficient and follow energy saving tips and tricks to ingrain some environmentally friendly habits.

Following energy saving tips is essential to lower your costs, but it is also important to decrease your ecological footprint.

With millennials and Gen Z nicknamed “generation green”, there is a strong focus on energy saving, and rightly so. However, global warming is rising more rapidly than ever, and the term ‘climate emergency’ is being used rather than climate change to highlight the situation’s intensity.

All industries such as HVAC are revolutionizing their technology to act on climate change. Since home appliances and devices are a major contributor to our energy consumption, utilizing smart devices such as smart thermostats or smart controllers for air conditioners can make a huge difference on your bills!

Let’s get right to it. Here are 21 energy saving tips that can easily help you decrease your energy consumption:

1. Use Energy Efficient Appliances

Energy efficient appliances are specially designed to consume minimum energy to complete the same tasks that you’d perform with normal appliances.  In addition, some

The United States Is Unprepared For The Heat Of Now – Let alone the future

Forget about Humans interaction with our Warming Climate. Think about the infrastructure we build  for the last hundred years where one hundred degree Fahrenheit days ARE NOT THE Norm. Now every State in the union will have days over 1 Hundred Degrees and maybe weeks over one Hundred Degrees. Bear in mind that Minnesota had fires this summer around the Northern Lakes Region for the first time in memory. What is it gonna be like when the phone lines and the power lines come down. What is it gonna be like when the roads blow up. I do not mean catastrophic. I mean disruptive. I think disruptive is worse.

Nowhere Is Ready for This Heat

The Pacific Northwest is melting now, but all across America the infrastructure we have was built for the wrong century.

By Robinson Meyer

The Portland Streetcar is 20 years old, making it relatively sprightly for infrastructure in the United States. Yet it was built for a different geological epoch. On Sunday, while Portland suffered through what was then its hottest day ever, the system started to melt. As the temperature reached 112 degrees Fahrenheit, a power cable on a major bridge warped, twisted around some metal hardware, and scorched. Elsewhere, the wires that run above the track expanded and sagged so much that they risked touching the train cars. By mid-afternoon, the streetcar system had shut down. The trams, which run on 100 percent renewable energy, seem to offer exactly the sort of urban fast transit that the country needs to reduce carbon pollution. But they were not prepared for—they could not withstand—one of the region’s first wrenching encounters with the remade atmosphere.

At first blush, there isn’t much to say about the “heat dome” settled over the Pacific Northwest like a shroud. Here is the story: It is very hot. Portland’s hottest three days on record have been the past three: The city broke its all-time record on Saturday (108 degrees Fahrenheit), smashed it on Sunday (112 degrees), and broke it again yesterday (116 degrees). Seattle-Tacoma International Airport also set an all-time heat record yesterday (108 degrees). Farther north, the temperature in the town of Lytton, British Columbia, yesterday reached 117 degrees Fahrenheit, or 47.5 degrees Celsius—the hottest temperature ever measured anywhere in Canada. America’s northern neighbor now has the same all-time heat record as Las Vegas, hundreds of miles to the south. Portland’s all-time record now exceeds the all-time records for Dallas, Austin, Houston, and Atlanta. It is very hot.

Singapore Solves A Serious Energy Issue – If only Bloomberg would get to it as well

Now if the Bloombergs of the world would tackle their issues, maybe the Earth would make some progress.

Solving the Global Cooling Problem

As air-conditioning sucks up more and more energy, Singapore finds a greener way to keep cool.

By Faris Mokhtar

In Singapore, close to the Equator, temperatures regularly rise above 32 degrees Celsius (90 Fahrenheit) — but inside the soaring glass greenhouses of Gardens by the Bay, the country’s award-winning botanical park, it’s a pleasant 24 degrees.

The daffodils and tulips of the flower dome, along with two dozen nearby towers that are normally full of bankers, shoppers, residents, hotel guests and gamblers, are chilled by what is probably the world’s largest underground district cooling system. It’s a giant air conditioner that is attempting to solve one of the biggest problems of global warming: How to stay cool.

(moving right along)

That means a massive drain on power — more than a third of the world’s electricity could end up being used to cool buildings and vehicles — with an equivalent jump in carbon emissions if, as is the case now, most of that extra generating capacity relies on fossil fuels.

The rise of global cooling has prompted research and development into ways to make systems more efficient using heat pumps, solar-power, evaporative coolers and other technologies. One of the most effective is to build a system that uses a large central plant that can cool several city blocks.

California Becomes 1st State to Require Solar Panels on New Homes. Here’s How It Will Reduce Utility Costs

Natasha Bach
Fortune

https://finance.yahoo.com/news/california-becomes-1st-state-require-181816746.html

California has taken the final step to be the first state in the nation to require solar panels on new homes.

The California Building Standards Commission on Wednesday unanimously upheld a May 9 decision to require solar panels on homes up to three stories. The requirement goes into effect Jan. 1, 2020.

Currently, just 9% of single-family detached homes in California have solar panels. But as the state pushes toward decreasing greenhouse gas emissions—and with a 2045 goal to transition to a fully renewable energy grid devoid of fossil fuels—this rule will help accelerate that progress. Aside from energy efficiency, solar panels reduce ozone-damaging household emissions, most of which come from natural gas-generated electricity.

In the long-term, solar panels benefit homeowners. While the upfront cost for building a home will increase—by as much as $10,000, according to the California Energy Commission, or as much as $25,000-30,000, according to home construction company Meritage Homes—long-term energy bill savings will be considerable.

Reuters reports that a homeowner could expect to save $19,000 in energy costs over 30 years, while Meritage Homes predicts reduced operating costs could amount to as much as $50,000-60,000 over a 25-year period.

Want To Save The Planet – Block the sun

It is a short article. So I will be brief. This is a film that reduces solar absorption by 10%. Combine that with a white roof and you got some major savings. Plus you dampen green house gases at the same time. HAPPY THANKSGIVING EVERYONE!

Heat-rejecting film could reduce air conditioning costs

It blocks 70 percent of incoming solar heat.

Steve Dent, @stevetdent

11.12.18 in Green

Climate change can be a vicious cycle when folks crank up the air conditioning during heat waves and add even more CO2 to the atmosphere. Scientists from MIT and the University of Hong Kong have developed a new type of window coating that could curb that trend. It remains highly transparent up to 89 degrees F (32 degrees Celsius), but beyond that, it becomes translucent like frosted glass. As a result, it reflects back up to 70 percent of the sun’s incoming heat, reducing interior temperatures and the load on your air conditioner.

To maximize heat blocking, the researchers inserted tiny water-filled spheres into a standard poly material. At temperatures starting around 85 degree F, the spheres start to shrink, squeezing out the liquid and forcing the poly fibers closer together. That gives the glass a frosted appearance, blocking 70 percent of the incoming heat while still letting a lot of visible light through.

Such films have been tried before but didn’t block heat that well. The MIT and Hong Kong teams realized that the water filled spheres needed to match the wavelength of infrared light responsible for most solar heating. After expanding the bubble size to 500 nanometers, the film became a much more effective heat-blocker.

Small Houses For Vets – Why not small houses for all the homeless

Don’t get me wrong. I think this is really good and really good work as well. But housing as seems obvious is the solution to homelessness. So why not house all the homeless in small houses. Hell for that matter house all the poor people that want them in small houses.

I have been at a loss for words for the last month. Things are going so well. I know Dotard is still President and many things are seriously messed up. But on the alternative energy front things just keep getting better and better. Don Blankenship actually made a fool out of himself and lost a primary vote for the Senate in West Virginia. Next week I may even get to report that Yucca Mountain is open for business. But for now, California hits one out of the park.

California regulators approve mandate for solar panels on new houses

 

May 09, 2018 | 12:10 PM
/

California regulators on Wednesday mandated that all newly built single family houses have solar panels, part of the state’s aggressive push to combat climate change.

The California Energy Commission voted 5-0 to approve the measure, which also applies to multifamily buildings of three stories or fewer. The mandate is set to take effect in 2020 and does not need the approval of the Legislature.

The requirement is expected to save consumers money in the long run through reduced utility bills, but also make a new house more expensive to purchase at a time many families already struggle to afford a mortgage.

In addition to the solar mandate, the commission approved new insulation and air filter requirements for newly built homes. In all, the new residential requirements are expected to make a single-family house $9,500 more expensive to build on average, but save $19,000 in reduced utility bills over a 30-year period, according to the Energy Commission.

Pakistan May Have Just Set a World Heat Record

Brian Kahn

High temperatures are forecast to reach the mid-80s this week in New York, and I’m dreading it. But I have a plan to stay cool: just thinking of how much hotter it is in Pakistan, which is in the middle of a blistering heat wave.

Temperatures reported to have cracked 50.2 degrees Celsius (122.3 degrees Fahrenheit) on Monday in Nawabshah, located about 127 miles northeast of Karachi. If confirmed, that could make the measurement not just the hottest ever recorded for April in Pakistan, but the hottest ever reliably recorded for April anywhere on Earth.

 “There was a 51.0°C reading reported from Santa Rosa, Mexico in April 2011 but this figure is considered of dubious reliability, so yes, the 50.2° reading is likely the hottest April temperature yet reliably observed on Earth in modern records,” Chris Burt, a weather historian, told Earther in an email.

Saudis Plan 200 GW Solar Power Plant – Twice as big as Chicago

Solar and Wind Power are on a huge tear. This is both in price, where coal is dead and natural gas is getting iffy. But in terms of availability and cutting edge technology. I see a future where generating electricity through renewables may be a same day thing and cheap as dirt. I know I am a dreamer but I am not the only one.

By the way, some people say that size doesn’t matter. I ain’t one of those.

What Saudi Arabia’s 200 GW solar power plant would look like—if placed in your neighborhood

Energy Shocks

April 01, 2018

Saudi Arabia has a plan to wean its economy off oil. In the biggest sign of what the future of the Gulf state would look like, Saudi Arabia’s crown prince, Mohammed Bin Salman, has signed a memorandum of understanding with Japanese multinational Softbank to build 200 GW of solar power by 2030 at a cost of $200 billion.

These are eye-popping numbers. If built, that solar-power plant will be about 200 times the size of the biggest solar plant operating today. It would more than triple Saudi Arabia’s capacity to produce electricity, from about 77 GW today.

With current technology, solar panels capable of generating 200 GW would likely cover 5,000 sq km—an area larger than the the world’s largest cities.

Electric Utilities May Be Doomed – If they haven’t invested in renewables they better start

Posted on by
Reply

The real important point from this article for me is that, ‘The die was cast around 1998, when GDP growth and electricity demand growth became “decoupled”’. In other words, for the last 2o years the utilities should have been investing in renewables and they did not. The point being that renewables are easier to turn “off” when you do not need them. If the utilities start investing heavily now in renewables they may survive. It is a horse race at this point.

https://www.vox.com/platform/amp/energy-and-environment/2018/2/27/17052488/electricity-demand-utilities

After rising for 100 years, electricity demand is flat. Utilities are freaking out.

The Tennessee Valley Authority is the latest to be caught short.

The US electricity sector is in a period of unprecedented change and turmoil. Renewable energy prices are falling like crazy. Natural gas production continues its extraordinary surge. Coal, the golden child of the current administration, is headed down the tubes.

In all that bedlam, it’s easy to lose sight of an equally important (if less sexy) trend: Demand for electricity is stagnant.

Thanks to a combination of greater energy efficiency, outsourcing of heavy industry, and customers generating their own power on site, demand for utility power has been flat for 10 years, and most forecasts expect it to stay that way. The die was cast around 1998, when GDP growth and electricity demand growth became “decoupled”:
