For this week’s article I am proposing an altered version of the first paper I wrote for tthe sustainable strategy seminar during the course of my MBA in Sustainable Business and Energy at Presidio Graduate School.
Now, according to Grist and Ecogeek, four African teenage girls created a generator that runs on pee, turning one liter of the liquid into no less than six hours of electricity.
Albeit we don’t know exactly how much electricity was created – and how much it required to be created – this is still something noteworthy.
The sunny – and hot, and dry – weather witnessed by Europe lately has one good point : Germany broke all records of solar photovoltaic generation with as much as 22 GWh. As Cleantechies reported :
” that amount of electricity fed into the national grid on Saturday (May 26) met around 50 percent of the country’s electricity needs. That is the same as 20 nuclear power stations at full capacity. “
” (…) At the same time of the year last year Germany was producing 14 GW per hour. Its total installed capacity is 26 GW. “
To EcoGeek : ” Semprius, a startup company manufacturing tiny concentrated solar cells that forgo any cooling systems has achieved a truly amazing leap in solar cell efficiency. “ This is truly exciting as ” The company was able to hit 33.9 percent efficiency with their solar panel, the first time a commercially-viable solar technology … Read more
Here are some great news for climate and quite bad news for America and Europe : China unveiled last week massive wind energy plans. The People’s Republic is willing to seriously expand the renewable energy industry. Indeed from the current 40 GW of capacity, it is planning to reach ” 200 GW, 400 GW and … Read more
According to an International Energy Agency official, a third of ALL global energy needs could be answered by solar energies within the next five decades. (photovoltaic, concentrated and thermal) And this could be a low estimate : as Climate Progress notes : ” Solar is clearly proving itself without a price on carbon. With an … Read more
Here is my latest post on CleanTechies, this time on wave and tidal energies : “According to a new study by the Carbon Trust up to 240 GW of capacity of marine energy could be installed worldwide by 2050.“ ” Out of these, 75 percent could be coming from wave, and the remainder by tidal … Read more
This is the title of an interesting article at GreenTech Media. Here are some essential quotes of it : ” Hydrogen. In green technology circles, just mentioning the word is enough to start an argument. “
” Hydrogen could become a ubiquitous source of electricity and heat, say advocates. Plus, it’s somewhat prevalent. Hydrogen remains the most abundant element in the universe (…) “
” Hydrogen advocates (…) readily admit the technology has not lived up to its promise. Virtually all of the experience to date seems to bolster the case of the critics.“
Despite its recent economic harshness, Iceland is rich as it is located on one of the world’s best geothermal hot spots. The potential is so large they are thinking about exporting electricity to neighboring European nations. As Ecogeek noted: “Iceland’s biggest utility, Landsvirkjun, has announced a plan to build the world’s longest undersea cable at … Read more
One of the most striking facts I learned from reading Crossing the Energy Divide is that decentralizing electric utilities would enable saving up to five trillion dollars. Here is a quote from the book (page 94) : ” WADE found that the world’s energy industries have a choice of spending 10.8 trillion in new central … Read more
Good news everyone ! To Cleantechies : ” The European Union will exceed its target of meeting 20 percent of its energy needs from renewable sources by 2020 (…). Twenty-five of the 27 EU nations will meet or exceed their national targets. “
This comes from a report from the European Wind Energy Association which notes that wind will be behind the vast majority of the electricity provided by renewables with 14 percent. This is quite a lot.
After checking among the 900+ articles in my database, this is not entirely new as the European Commission itself announced it in March 2010.
Geothermal energy is seldom mentioned among renewable energies as solar and wind energies get the lion’s share of the news. However, geothermal is one of the rare sources that can deliver electricity 24/7. To CleanTechnica : ” The geothermal industry has begun an unprecedented expansion starting this year, as a record 7, 875 MW of … Read more
