About fifteen years ago, humanity realized that if it does not want to be like the proverbial frog – which was boiled in milk for the sake of momentary comfort – then we must immediately stop burning minerals that create a greenhouse effect. Indeed, since the beginning of the 20th century, the average annual temperature on the planet has increased by 1 degree. If it continues this way, then in the 21st century it will rise by another 4 degrees! Fearing this, mankind frantically began developing green energy. Apparently, we have achieved impressive results. The total installed capacity of renewable electricity has doubled over the past 10 years and amounted to 2,537 GW. There are even countries – Iceland, for example – where the share of green energy was 100%! Costa Rica and Austria are closing in, while in Germany the share of green energy exceeds 50%. We seem to be crawling out of the warm milk, don’t we?

Perovskite solar cells might revolutionize how humans generate energy from sunlight.
https://brilliant.org/ElectricFuture
First 200 people get 20% off annual premium subscription.
In this video we’ll explore the world’s fastest improving new solar technology, and provide an exclusive peek inside the lab of a team working on this breakthrough material.
Imagine an inexpensive solution of perovskite crystals that can make a photovoltaic cell so thin, that just half a cup of liquid would be enough to power a house. A solar panel so lightweight, that it can be balanced atop a soap bubble. That is known as the holy grail of solar energy. So when will we see perovskite solar panels used for a solar power system for your home? Maybe sooner than you expect.
Currently, only 2% of global electricity comes from solar power. And 90% of that, comes from crystalline silicon-based solar panels, the dominant material technology.
While abundant, silicon has downsides related to efficiency, manufacturing complexity, and pollution that prevent it from being an absolute no brainer. Emerging thin films like perovskites present a bright future. Imagine solar cars like a solar tesla, solar yachts, or a solar plane.
Solar cell technologies can be classified into two categories, wafer-based or thin-film cells. Perovskites are the leading contender in emerging thin films. Topics covered in this video include applications, perovskite crystal structure, working principle of perovskite solar cells, efficiency limits, multi-junction solar cells, shockley-queisser limit, how solar works, solar simulator, band gap, manufacturing, vapor deposition, how solar panels are made, and the future of solar power.

Steps:
1. The solar panel array is installed by securing four massive earth screws into the ground to act as a base.
2. The solar panel array is then craned off of a truck into place on top of the earth screws.
3. A trench is dug from the array to the house. Conduits are placed in the trench containing a hot, ground, neutral, and a Cat5 cable. The Cat5 cable allows the system to take in weather and location data.
4. Once the array is secured to the base and wired up, the latitude and longitude of the area is programmed into the system and it can be powered up.

Kevin O’Connor and a specialist perform a whole-house energy audit. (See steps below.)
SUBSCRIBE to This Old House: http://bit.ly/SubscribeThisOldHouse
A professional whole-house energy assessment will examine your home’s insulation, appliances, lighting, and heating & cooling systems. It will also determine how airtight your home is. At the end of the assessment, the technician will provide a written report identifying and prioritizing the steps you can take to save energy. For more information about energy audits, visit this U.S. Department of Energy website [https://bit.ly/3f2j252].
Steps for How to Perform a Whole-House Energy Audit:
1. Check the energy rating on each appliance and light fixture. Look for Energy Star label or other low-usage ratings. Replace older products that are wasting electricity.
2. Inspect the water heater, and make note of any leaks, rust spots or lack of insulation. Also, check the heater’s age and energy efficiency.
3. Run a combustion safety test of the steam boiler with a combustion analyzer.
4. Use the analyzer to measure the temperature and ratio of gases inside the flue pipe.
5. Next, drill a small-diameter hole in the flue pipe, then use the analyzer to measure the air pressure and to ensure that the boiler is drafting (exhausting) properly.
6. Hold a smoke stick beside the flue to confirm that gases aren’t leaking back into the basement.
7. Install an electric blower door in the front doorway to test for air leaks throughout the house.
8. Close all windows and doors in the house. And shut fireplace dampers, then turn on the blower fan.
9. Use a smoke stick to check for leaks around doors, windows, fireplaces, vents and chimneys.
10. Take a handheld infrared sensor and check for temperature differences on the interior walls and ceilings. A cool spot is evidence of poor insulation or an air leak.
11. Use the infrared sensor to check for temperature changes around pull-down attic stairs.
12. Climb into the attic and inspect insulation in the attic floor; it should be at least 12 inches deep. Add more insulation, if necessary.
13. If the existing insulation is damaged or badly compressed, remove it and install new insulation.
14. Seal air-leaking gaps around the chimney with fire-rated flashing and caulking, then insulate around the chimney.[BR]
15. Seal all penetrations and gaps in the attic floor with expanding polyurethane caulk.
16. Make or buy a rigid-foam attic stair cover and install it over the opening for the pull-down staircase.
Our energy audit was conducted by Next Step Living.
The Infra-red camera used in the audit is manufactured by FLIR [https://www.flir.com/].
The smoke pencil and inflatable chimney damper are manufactured by Chimney Balloon [https://www.chimneyballoon.us/chimneyballoon.html].

Energy is one of the leading issues in the upcoming U.S. Presidential Election. Supporters of the Green New Deal are shoving this idea to the top of political headlines and are what today’s guest calls “Champagne Socialists”—those who push their ideologies unto others but aren’t willing to get their hands dirty.
We all want a better world for future generations than we have today. But to have an electrical world powered by wind and solar, you need rare-earths, silver, copper, cobalt… you need many different and expensive materials in vast quantities.
Marin Katusa, one of the world’s most successful resource venture capital fund managers, overseeing some of the largest funds in North America, says, “There’s some seriously big money to be made in this trend. And there’s going to be a lot of mistakes. There’s going to be a lot of scams. There’s going to be a lot of wasted government money, just like you mentioned, Solyndra and other deals from Obama’s green dream. But just like I proved it before, there’s going to be incredible assets here that there’s a way to play it.”

Richard Trethewey checks out an Idea House in development and learns about energy efficiency building techniques.
SUBSCRIBE to This Old House: http://bit.ly/SubscribeThisOldHouse.
Richard Trethewey goes to Devens, MA to visit a new house with advance building techniques. He meets builder Dan Gainsboro who says the entire heating season will only cost 00 or less for this new house—considerably lower than what our homeowners were paying to heat their house. He shows Richard how the houses in the development are built using 2×6 walls with insulated panel sheathing for a water and air-tight shield. Walls are insulated on the inside and the window openings are wrapped with flashing tape and even the headers are insulated. They used triple glazed windows throughout. The finished Idea House is a lovely small scale home with an open floor plan. The light fixtures use LEDs and the appliances are all Energy Star rated. In the well-insulated basement, there’s no mechanical room because mini-split heat pumps are used to heat and cool the entire house. And finally, Dan shows Richard the solar panels on the south facing roof of the garage. On a sunny day, the panels generate enough electricity to power the house for a family of four.

Andrew Clennett is passionate about the potential of a new energy source, one that could fuel our lives cleanly and sustainably. After many years travelling the world developing energy projects in such places as Brazil, West Africa, North America, Australia and Europe, Andrew moved with his family to New Zealand in 2012 to take on the role of General Manager of Todd Energy’s operations.
Throughout his career Andrew has had a passion for all things energy. He is driven by its potential to unlock societal growth in both developed and developing countries, together with the need to balance this with the impact of the current energy mix on our planet.
In 2017 he chose to use his skills to accelerate the transition to a new energy paradigm and became a founder and CEO of Hiringa Energy, a company developing hydrogen generation and supply infrastructure and zero emission solutions. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at https://www.ted.com/tedx Video Rating: / 5
Advanced CAES is a new iteration of an old technology that’s able to harness air’s elastic potential to store energy until it’s ready to be used, which could be a huge game-changer for renewable energy.

In a world in desperate need to go carbon-free, solar, wind, and renewables are the future, but our present ability to store their excess energy falls short.
Of the many possible solutions, compressed air seems to be sweeping some in the energy sector off their feet. Compressed air energy storage, or CAES, takes advantage of air’s ability to be stored in the form of elastic potential energy until we’re ready to use it.
We’re currently grappling with modernizing the world’s power grid and a major challenge is to make renewables reliable in every situation, not just on sunny, cloud-free days. That’s because renewable energy needs to be “firmed,” meaning that it can give energy on-demand in every situation.
CAES is lauded by some in the energy sector as a sustainable way to make renewables the world’s go-to energy source, who say that this storage system could be the sustainable energy storage we’ve all been waiting for. The technology converts electrical energy into high-pressure air, which is later released to drive a turbine.
And while theoretically, CAES could be a cheaper and more sustainable alternative to batteries, there are still a few things holding it back. But an updated version of this old technology, developed by the Canadian company Hydrostor, could give CAES the boost it needs to succeed.
Find out more about Hydrostor’s plans to bring compressed air energy storage into the mainstream on this Elements.

Storing energy in compressed air could finally become cheap enough for the big time
https://qz.com/1711536/canadian-startup-hydrostor-is-storing-energy-in-compressed-air/
“Having to use an underground cavern means Hydrostor can’t build its plant just anywhere. But VanWalleghem says that, unlike the strict geological needs of oil-and-gas companies, compressed air can be stored in many types of rock formations. That means Hydrostor can technically build its plants on 70% of the planet’s landmass.”
Let’s store solar and wind energy – by using compressed air
http://theconversation.com/lets-store-solar-and-wind-energy-by-using-compressed-air-103183
“Energy is already stored, of course, in batteries or various other technologies. Even reservoirs can act as huge stores of energy. However nothing that exists or is in development can store energy as well, and as cheaply, as compressed air.”
The grid of the future will be powered by … giant subterranean bagpipes?
https://www.digitaltrends.com/cool-tech/hydrostor-grid-of-the-future/
“Right now, the world relies predominantly on two different grid energy storage techniques: pumped/dammed hydroelectricity, and batteries. Other methods do exist, but batteries and “pumped hydro,” as they call it, are by far the most common.”

It’s not in the papers but a silent revolution is moving across the world. Renewable energy is becoming cheaper than from fossil fuels. It means that progressively the choice for wind and solar energy is no longer an ethical one but an economic one. And this will speed up the transfer to renewable energy.
In countries like Brazil, Australia, Chile and parts of the United States people consider renewable energy because of financial reasons. The price of solar and wind energy will continue to drop and in more countries renewable energy will occur.
A surprising newcomer on the market is Morocco, where the government expects that in 2020 more than 40 percent of the energy could come from solar energy.
