solar water heat


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

Obsession

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.

Residents Move Into America’s First Solar Powered Town

Residents will live in solar powered homes and ride around the community in self-driving, solar-powered shuttles. Babcock Ranch outside of Fort Myers, Florida, has been in the making since 2005. A city of 50,000 is forecast.
January 18, 2018, 1pm PST | Irvin Dawid

“Families are starting to move into what is being called America’s first solar-powered town,” announces John Dickerson for CBS This Morning on Jan. 16. “Babcock Ranch, about half an hour northeast of Fort Myers, Florida, is supposed to produce more energy than it consumes once it’s finished.”

Developer Syd Kitson is building 20,000 homes for a projected 50,000 people, states Dickerson in the newscast video accompanying the article.

There are more than 300,000 solar panels spread across 440 acres there, producing enough electricity not only for the town, but also the surrounding areas, reports CBS News’ Manuel Bojorquez.

One critical energy element lacking in the solar-powered community will be adequate energy storage to allow the city to be truly self-powered:

The town doesn’t run on solar power all the time. At night, when the sun is down, it has to draw from the traditional electrical grid. Kitson says the technology for storing all that surplus energy the solar cells generate during the day is still too costly.

I am so amazed by this, that I do not know what to say. I wish these type projects had started 30 years ago. You would say, impossible. I would say the technology would have been different and the work harder, but it could have been done. Still I am so proud of Renault and I hope more companies try this out. GO Renault!

Renault’s ‘smart island’ runs on wind power and recycled batteries

The experiment in Portugal aims to prove you can live without fossil fuels.

Renault has launched a “smart island” in Portugal that uses its Zoe electric vehicle, home batteries, smart charging and vehicle-to-grid (V2E) energy storage to run without fossil fuels. The idea is to make the Madeira island of Porto Santo energy independent and stimulate renewable energy production. “[We want] to build a model that can be carried over to other islands and cities,” Renault Electric Vehicle Director Eric Feunteun told Engadget.

Unlike Tesla’s massive Powerpack installation, the Renault project is more of a community endeavor on the small (16 square mile) and sparsely populated (5,483 inhabitants), tourism-oriented island. It will unroll in three phases: In the first, 20 fortunate Porto Santo volunteers will get 14 Zoes and six Kango Z.E. utility vans to use every day. They’ll benefit from 40 new connected public and private charging stations set up by Renault and local utility Empresa de Electricitade da Madeira (EEM).

“Let’s say you come home from work at 7 PM with a decent charge left, and only need two to three hours of charging,” said Feunteun. “The smart charging system we’re testing will decide when the best time to do that is, based on usage, energy availability and other factors. Then, it can charge up to eight times a day in chunks as small as 15 minutes.”

I agreed to publish this here because it is such a different perspective then the one I have or CES has. We tend to blame builders for not just serving up top notch energy efficient residences. Then there is the issue of retrofitting. As always this is no endorsement of Ryan or his Real Estate firm. Believe me I have no intention of buying a home in Alaska.

 /
Now, a “green home” really isn’t all that green when observed on its own, but the fact
remains that most of new construction and existing homes are going to be detached
single-family residences. This means that we need to do the best we can with the hand we
have been dealt, and that would suggest that incremental improvements across the board
may be the best option in terms of reducing waste. Recent trends in US real estate have
affected what buyers are looking for in some positive ways, but there are still far too few
green homes available for buyers who want this option.!That makes it a frustrating search
for potential green home buyers, and discourages them from truly setting their sites on a
home that works for them. Additionally, because they aren’t making their voices heard,
many builders are not working to make homes that meet green specications (beyond the
bare minimum). They don’t realize the level of demand that would be there, if buyers felt
they would have the option.
 /
More Buyers Should Push for Green Homes
 /
There’s really one way to remedy the issue: buyers who want green homes should push
for them across as many channels as they can. If more buyers continue to ask for green
homes, more builders will produce these homes out of necessity. But buyers need to be
the catalysts in both demand and advocacy aimed toward other potential green buyers.
More of them want green homes, but they back down when they see these homes aren’t
available. Builders and sellers both need to know the value of creating these kinds of
homes or making changes to existing homes, so buyers will be more likely to purchase
those homes instead of other options. This might mean more negotiations with sellers and builders, and it will likely come at an increased cost — costs that will likely be recouped over time, but another upfront cost nonetheless.
 /
What are Buyers Looking For?
 /
When the average buyer!wants a green home, they don’t necessarily require one that’s
completely off grid. Some buyers will seek these out, but most will be looking for energy
efifciency, sustainable materials, and a smaller carbon footprint than what would be seen
with a standard house. In many cases, that’s enough to entice buyers to make a purchase,
and to keep them happy with the home they have selected. It also depends on the area of the country and the local market, because some buyers want and need different options due to weather or other factors.
 /
More Demand Will Require an Increase in Supply
 /
The more buyers start asking for green homes, the more likely it is that builders will create them. Sellers will also start making changes to the homes they are putting on the market, in order to entice buyers to come see their home instead of a different one. That’s an important consideration, too, since sellers may need to retrofit their homes in some ways and add options that they would not have chosen to put in if they were remaining in the house. Some green living changes can be expensive, but these changes don’t always have to be costly. There are lower priced options, as well.
 /
Trends are Moving in the Right Direction, at Least
 /
Even though there are still far too few green homes, and even though buyers aren’t making their voices heard as loudly as they could, the trend of green living is still going in the right direction. More buyers see the value of it, and more builders and sellers are starting to make changes in that direction. There is still a long way to go before energy efficiency and reducing waste becomes the standard for new homes and improved existing homes, but a larger pool of buyers demanding these features can help move the needle bit by bit.

Swiss vote for gradual nuclear phaseout

15:10 CEST+02:00
The Swiss voted on Sunday in favour of a massive overhaul of the country’s energy system by gradually replacing the power from its ageing nuclear reactors with renewable sources.
A full 58.2 percent of Swiss voters supported the shift, according to a final tally after Sunday’s referendum, with only four of the country’s 26 cantons voting “no”.
“This is a historic day for the country,” Green Party parliamentarian Adele Thorens Goumaz told public broadcaster RTS.
“Switzerland will finally enter into the 21st century when it comes to energy.”
The move has been in the making since shortly after Japan’s Fukushima nuclear plant was destroyed in the March 2011 tsunami disaster, when the Swiss government decided to gradually close its nuclear plants.
Instead, it aims to increase reliance on hydraulic power as well as renewables like solar, wind, geothermal and biomass.

I was going to write about Germany making 85 percent of its power with renewables on a particular day. As fun as that is this is better. Egypt is going to invest billions of dollars in solar (and wind?). That is so exciting. I hope the rest of the countries of the Middle East follow suit.

Egypt looks to the future with renewable energy plan

By Ahmed Megahid, The Arab Weekly   |   May 15, 2017 at 10:33 AM

CAIRO, May 15 (UPI) — The vista in the central province of Minya is as empty as far as the eye can see except for rows and rows of solar panels and the blue sky above.

The panels are helping Amr al-Saad’s 8-month-old power sta­tion address the worsening issue of brownouts and blackouts in the area.

“A few years ago, power supply was intermittent, which made the life of the residents of the province very tough,” he said. “That is why I decided to establish my project where it is most needed.”

After generating electricity, Saad’s station feeds it into the na­tional grid where it is used to power houses, farms and workshops in Minya’s villages.

Saad’s project, which cost $100,000 and produces 650 kilo­watts of electricity each month, is part of a national drive to reduce Egypt’s dependence on fossil fuels by shifting to renewable energy. Egypt plans to produce 20 percent of its electricity from renewable sources by 2022 and 37 percent by 2035. It is an ambitious plan given that just 3 percent of electricity produced annually in Egypt today is from renewable sources.

It has taken the last 30 years to get to the point where we can have this conversation. Is it in time? I do not know, but it sure feels good.

Solar Power vs. Wind Power Pros and Cons

Solar Power vs. Wind Power Pros and Cons

After doing some research on renewable energy systems or alternative energy systems as many will call them, I wanted to get the information out there as far as the advantages and disadvantages of the 2 main renewable energy systems, wind turbine generators and photovoltaic solar panels.

Both solar panel and wind generator systems are similar as far as how they are setup. You can have the wind generator grid tied or off grid, same as solar panels. Both the solar panel (photovoltaic panel) and wind generator will need a battery bank if you are using an off grid system. Both of these renewable energy systems will produce clean energy and help the environment as well as save you money in your home!

Advantages and Disadvantages of Wind Generator Systems and Solar Panel Systems

Now onto some of the advantages and disadvantages of each alternative energy system. None of this information is from my own personal experience as I do not have the financial funds to support the research. So the information about these renewable energy systems have came from researching the internet, talking to people that have these alternative energy systems, and of course some calculations of my own (prices, efficiency, etc.).

Wind Turbine Generator System Pros and Cons

The main advantage of wind generator is that they can produce electricity day or night as long as there is wind. Wind generators need less space on your land to produce sufficient electricity. Wind generators are able to produce more electric for the same price. If you spend $1,000.00 on wind generator you can produce 1kW – 2kW, with solar panels you may only produce around .5kW – .75kW with the same $1,000.00. Wind generators have moving parts, so there is always wear and tear on these moving parts. Bearings can go bad, propeller blades can be struck by objects, and heat may be generated. Your wind generator will be installed on a tower or pole of some sort to gain height where there is more wind, allowing lighting to possibly strike your wind generator. As wind hits the propeller blades there will be noise created, think of a fan and how they sound, or even taking a rope and swinging it fast in circles. You will get some of this noise from your wind generator. The propellers of the wind generator can also produce shadows flickering. Birds can get killed from flying into your wind generator’s propellers. There are vertical wind generators which will prevent this. So the quick break down of the wind generator system:

Natural gas is cheap. Solar Photovoltaics are even cheaper. The job prospects in renewables are growing as fast as miners jobs are falling. Donald Trump may think he is all powerful but even if the Russian mob boss Putin joins in, China, India and Australia never will. Seems to me that is the end of the story.

http://www.computerworld.com/article/3166897/sustainable-it/report-1-in-50-new-us-jobs-came-from-solar-last-year.html

Report: 1 in 50 new U.S. jobs came from solar last year

Employment in the industry rose in 44 states and is expected to continue growing

One out of every 50 new U.S. jobs last year came from the solar industry, with growth in that industry outpacing the overall U.S. economy by 17 times, according to a new report.

Overall, there were 260,077 solar workers in 2016, representing 2% of all new jobs, according to The Solar Foundation’s Solar Jobs Census 2016.

Solar employment increased by more than 51,000 workers, a 25% increase over 2015, according to the report. Solar industry employment has nearly tripled since the first National Solar Jobs Census was released in 2010 — rising at least 20% annually for the past four years.

Along with growth in solar and other forms of renewables, energy storage is a rapidly growing industry, comprising 90,831 jobs — of which 47,634 are focused on battery storage.

To Not talk about how disastrous Trump’s Presidency will be for the environment and the energy industry I decided to return to my roots in the residential market. Todays article is a bit old but its message is timeless. We have been concentrating on single devices like furnaces, refrigerators, windows seen as a whole instead of a holistic approach to a house.

https://www.greentechmedia.com/articles/read/the-real-problem-with-energy-efficiency

We’re Doing Residential Energy Efficiency All Wrong

Utilities are now spending nearly $7 billion a year on energy-efficiency programs. It seems we have little to show for it aside from expensive consultants who will model any results you would like.

These programs tend to focus their marketing on the energy savings or money savings from the projects. Consumers don’t care. If they did, we would see geometric growth instead of a resounding “meh.”

Others focus on better financing products, slicker sales pitches, faster energy audits, higher rebates or any of a myriad of other things.

In the residential sector, none of these are the problem. The lack of sales is the problem.

Projects are not being sold and implemented in substantial numbers. We need to slow it down, build relationships with consumers and educate them, learn and think systemically about the problems they have, and arrive at solutions that fit homeowner budgets.

I heard this on NPR and I just had to put it up here. I especially like that people like Bruce Rauner and Donald Trump are so out of touch with their base. But what does it say about the Democrats.

https://www.greentechmedia.com/articles/read/california-republicans-are-5-times-more-likely-to-buy-solar-than-democrats

California Republicans Are 5 Times More Likely to Own Solar Than Democrats

Republican voters and elected officials are generally considered hostile toward renewable energy. That’s likely because many prominent Republicans deny humanity’s contribution to climate change and oppose subsidies for clean energy technologies, despite the fact that fossil fuel industries benefit from billions of dollars in tax breaks.

Instances like the snowball toss made by Republican Senator James Inhofe, chairman of the Environment and Public Works Committee, coupled with his record of voting against clean energy legislation, help to cement the perception that conservatives widely oppose the adoption of low-carbon technologies like solar and wind.

This year’s GOP platform states, “We encourage the cost-effective development of renewable energy sources — wind, solar, biomass, biofuel, geothermal and tidal energy — by private capital.” However, Republican presidential nominee Donald Trump has repeatedly bashed the clean energy sector, called climate change a hoax created by the Chinese, and recently called the solar industry “a disaster.”
