Here’s how they did it, and how we can too
This is what can happen when citizens and government agree that it’s worth spending a bit more for clean, carbon-free power:
German solar power plants produced a world record 22 gigawatts of electricity – equal to 20 nuclear power stations at full capacity – through the midday hours of Friday and Saturday, the head of a renewable energy think tank has said … Norbert Allnoch, director of the Institute of the Renewable Energy Industry in Muenster, said the 22 gigawatts of solar power fed into the national grid on Saturday met nearly 50% of the nation’s midday electricity needs 유튜브 영화 다운로드.
That’s right—half of all of Germany was powered by electricity generated by solar plants. That’s incredible. It was also world record-breaking 드롭 박스 오프라인 다운로드. Germany is pretty much singlehandedly proving that solar can be a major, reliable source of power—even in countries that aren’t all that sunny 다운로드.
And it’s the result, primarily, of two forces:

Unlike much of the rest of the economy, the solar industry is growing rapidly 다운로드. New solar installations in California jumped by 21 percent last year. An increasing amount of that growth is from “solar leasing.”
What’s commonly called “solar leasing” is now the most popular way for homeowners to install solar electricity 이클립스 플러그인 다운로드.
A solar company installs the panels for the customer for free or for a minimal cost. Then it sells the consumer the electricity for about 10 percent less than local utility rates 액티브스퀘어 다운로드.
SolarCity CEO Lyndon Rive, “before solar was more designed to those who could afford a large upfront cost of $20,000 to $25,000. Now the average person can go solar and just start saving money, there’s no investment.”
Rive says the option is so popular that in some markets his company has a waiting list of 4 to 6 months 다운로드.

Liquid Metal Battery Corporation, an MIT spin out that’s developing new technologies for electricity storage, has raised $15 million in funding from Khosla Ventures, Total and Microsoft co-founder Bill Gates 더 이퀄라이저 2 다운로드. The technology behind the company was developed by Dr. Donald Sadoway (his famous TED Talk), a professor at the Massachusetts Institute of Technology who was recently named one of Time Magazine’s 100 Most Influential People in the World 해커스 인강 pc 다운로드.
“Large-scale electricity storage will be a critical part of reinventing the global electric grid infrastructure, and LMBC has developed the most innovative chemically-based solution that we’ve seen,” said Andrew Chung of Khosla Ventures 다운로드.
Bill believes that creating large-scale batteries to store energy is a critical problem to solve if solar and wind energy are to become mainstream 다운로드. In this video, Bill and MIT Professor Donald Sadoway discuss the importance of new battery storage technology and Sadoway’s focus on the development of a “liquid metal” battery 다운로드.

To get more technical, the liquid in the all-liquid battery is molten salt and liquid metal, which:
“…avoids cycle-to-cycle capacity fade because the liquid electrodes are reconstituted with each charge – similar systems have operated in a lab environment for more than 17 months with daily cycling and no reduction in performance 재밌는 게임 다운로드. The molten salt electrolyte combines high conductivity with abuse tolerance at low cost. Self-segregation due to three immiscible liquid phases of different densities (e.g Crush download. oil and water separation) allows for robust operation and ease of manufacture. Together, these attributes will enable the liquid metal battery to exceed 70% round-trip AC efficiency for over a decade without degradation.”

There will be a stunning partial solar eclipse on Sunday, May 20th 동물 소리 다운로드. The moon will begin shrouding the sun at 5:27 p.m. (PST) and will cover 83 percent of the sun’s surface at 6:40 p.m. The eclipse will take place while the sun is sinking toward the horizon, out over the ocean 호텔 델루나 7회 다운로드. It’ll be easy to see, if skies are clear.
Do not — repeat, do not — look at the eclipse with your naked eye or with materials that don’t protect your vision from UV and infrared radiation 입사지원서 다운로드. You risk permanent and serious damage to your vision if you don’t use the proper safety equipment to view a solar eclipse, and the damage can occur within seconds 마인크래프트 자바 에디션.

I’ve been seeing a lot more solar panels installed on homes. Which has me wondering, what is the impact on cost, inconvenience, and utilities 외산폰 유심 다운로드.
Scott over on the Zero Waste Blog has the perfect, written-by-an-engineer, write-up 곰돌이 푸. It is worth reading the whole thing, but here is a meaty excerpt:
So what has the impact been? Well, we did actually turn up the heat – so I don’t have to wear the puff jacket all the time 팟플레이어 영상 다운로드. But despite the relaxation of the “thermostat tyranny”, we have seen a huge decrease in our month bills:
- For our first full month (FEB 13 to MAR 14): We used negative 5 kWh (our meter ran backwards) 다운로드. Of course, in Northern California, we had a sunny, warm February, with virtually no rain. For the same period in 2011, we used 601 kWh.
- For the 2nd month (MAR 14 to APR 13): We used 141 kWh 다운로드. Last month was cold and very rainy (i.e., less solar power), we had guests and turned up the electric heaters. For the same period in 2011, we used 567 kWh 뱀파이어 다이어리 시즌 1.
- Bottomline: Our total electric bill for two months is $17.50, plus $8.88 in unavoidable taxes, etc. For comparison sake, the same two months last year cost us $207.28 설리 리얼 다운로드.

– …illustrate the variability of wind and solar generation relative to the comparatively smooth output from other generation sources
– Power produced by geothermal, biomass, biogas, and small hydro generators can be easily dispatched, meaning it can be either increased, decreased, or controlled to remain fairly constant mtkv26b1.
– Wind resources are often more available at night.
– Solar power is not generated until the sun comes up, and can increase and decrease quickly as the sun rises, sets, or is blocked by cloud cover 대항해시대 4pk 다운로드. However, much of California’s utility-scale solar capacity is based on concentrating solar technology, which embodies enough thermal storage to continue generating power for a few hours after the sun goes down
– The variability of wind and solar power generation leads to challenges in power system operations and planning 다운로드.
– The contribution towards total generation from eligible renewable resources also varies seasonally. For the dates charted above, the amount of renewable generation as a percentage of the total generation ranges from 8% on Oct 18, 2011 to 14% on May 9, 2011 c# pdf 파일 다운로드.

100% of Minnesota’s electricity generation needs can be met by wind and solar sources combined with improvements to the state’s electric grid system and energy efficiency policies, according to a report released today 다운로드.
Researched and written by Dr 아츄 mp3 다운로드. Arjun Makhijani and Christina Mills of the Institute for Energy and Environmental Research (IEER) and Dr. M.V. Ramana of Princeton University.
Minnesota’s electricity sector currently accounts for over one third of the state’s greenhouse gas emissions 이카루가 다운로드. State policy is to reduce emissions by 80% by 2050.
“A significant change in electricity generation sources is clearly needed to achieve that goal,” Dr 다운로드. Makhijani explained. “Fortunately, wind and solar can provide 100% of Minnesota’s electricity. These currently available technologies also offer significant job creation and economic development opportunities.”
The notion that solar and wind energy cannot be the mainstay of an electricity generation system because they are intermittent is incorrect…it is technically and economically feasible to meet the entire 2007 electricity demand of Xcel Energy [in Minnesota] using only renewable energy generation combined with storage technology and energy efficiency improvements 다운로드.
The renewable energy mix would include approximately 13,000 megawatts of wind power and 4,600 megawatts of distributed solar PV…would pump more than $90 billion into the state’s economy and create 50,000 jobs 다운로드.
With the combination of new renewable energy and significant energy efficiency, electricity rates rise slightly but Minnesota ratepayers are held relatively harmless 다운로드.
The conventional notion of a “peak load” needs to be replaced in designing an electricity system with a high proportion of solar and wind energy…The crunch time may be during periods when the wind and solar supply are low relative to demand 다운로드.

We want to transform an abandoned trolley terminal on the Lower East Side of Manhattan into the world’s first underground park, called Lowline 한국드라마 다운로드.
This space is quite large, by New York standards: 60,000 square feet, or 1.5 acres. It was built in 1903 as a trolley terminal, for streetcars traveling over the Williamsburg Bridge, and has been out of operation since 1948 다운로드. We fell in love with the site because of its architectural details: old cobblestones, crisscrossing rail tracks, vaulted 20-foot ceilings, and strong steel columns 다운로드.
To build this park, we’re planning to use a cutting-edge version of existing technology– which we’ve already built in prototype 지방의 누명 다운로드. It uses a system of optics to gather sunlight, concentrate it, and reflect it below ground, where it is dispersed by a solar distributor dish embedded in the ceiling 킹스맨 유료 다운로드. The light irrigated underground will carry the necessary wavelengths to support photosynthesis– meaning we can grow plants, trees, and grasses underground 다운로드. The cables block harmful UV rays that cause sunburn, so you can leave the SPF-45 at home. Sunglasses optional (for cool kids).
We think a year-round public space will be valuable for everyone 꽃보다 청춘. Farmers markets and vendor stands can feature fresh produce and locally made goods, supporting local and sustainable businesses. Art installations, concerts, and performances can help showcase the incredible creative spirit of the Lower East Side 봄의왈츠. Youth programming and educational opportunities can offer rich experiences for kids and parents. And a safe haven from the hectic feel of Delancey Street will serve as relief in a very car-centric corner of Manhattan 웨이보 영상 다운로드.
When it’s really cold, or pouring rain, how much fun is it to hang out in Central Park? The High Line? Not so much. The LowLine can be the 21st century answer to traditional parks: instead of building up, let’s build down 다운로드!
Los Angeles ranks second in the state in terms of the number of solar installations on residential, commercial and government buildings, with just over 4,000 projects installed dx11. Los Angles is also second in the state in terms of the total amount of solar electricity generated, measured in capacity, with 36 megawatts.
“The good news is Los Angeles is closing in on San Diego’s lead as America’s #1 solar city,” said Michelle Kinman 맥스큐 pdf.
Every megawatt of solar power installed in the Los Angeles area prevents the emission of nearly 700 pounds of smog-forming pollution per year.
A recent report by the Solar Energy Industry Association shows that California is home to over 3,500 solar companies that employ more than 25,000 people 무료 크리스마스 카드 다운로드.
In the past two years, Los Angeles has nearly tripled the amount of rooftop solar installations. From 1999 through 2009, Los Angeles installed just over 1,000 solar rooftop systems, totaling over 13 MW 다운로드.
Governor Jerry Brown has called for a significant expansion of California’s rooftop solar market by putting out a vision of installing 12 gigawatts (a gigawatt is 1000 megawatts, or twelve times California’s current solar rooftop market) by 2020 다운로드.
