Cleantech could help cities save $17 trillion
Smart infrastructure choices from cities worldwide would save them $17 trillion (15.2 billion euros) by 2050. The solutions – renewable energy, public transportation, energy efficiency – are not new but the lens of this new study is interesting.
Green and blue at the same time with Biosolar Roof
What I love about blogging is coming back to old posts with new developments and ideas. Years ago I was wondering what was the most sustainable : blue roofs (with solar panels) or green ones. Some people combine both ideas and this is a GREAT idea.
Mosques are going solar too
I previously wrote that there are solar panels on the Vatican and some churches. Likewise, I reported that Christians are urged by to act on climate by Pope Francis. Now, Muslims are also starting to cover their mosques with solar panels too.
Inventors of the blue LED awarded the Nobel prize
This year’s Nobel prize in Physics is all about energy efficiency as it was awarded to three Japanese scientists for their invention of the blue LED. This enabled the world to have super efficient LED light bulbs.
Soon on your windows : invisible solar panels
What if solar panels were completely transparent ? They could be placed over windows and could enable us to have self charging smartphones. Now that’s something great.
A billion dollar a day invested in efficiency
365 billion Dollars (approx. 278 billion euros) : this is the money that was spent on energy efficiency around the world in 2012 according to a recent study the leading consultancy Ecofys did for HSBC.
A low tech and natural air conditioning system
I like Treehugger for coming up with great designs that could change a bit the world we are living in. One of their latest finds was a natural air conditioner that uses clay and evaporation. As Treehugger noted : ” Thibault Faverie‘s Cold Pot is a natural and simple air conditioner that uses clay and… Continue reading A low tech and natural air conditioning system
Energy efficiency brings huge returns on investment
You must know if if you have been reading this blog : albeit it is not as ” sexy “ as renewables, energy efficiency is simply a must as we embark our societies and economies on a journey towards sustainability. Here is further proof as Cleantechnica notes : ” Energy efficiency retrofits (…) created a… Continue reading Energy efficiency brings huge returns on investment
Five famous buildings with solar
What the common point between famous buildings around the world such as the White House in the United States, the Vatican, the Taj Mahal in India, the Burj Khalifa in the United Arab Emirates and the Eiffel Tower in France ? You give up ? They are all at least partly powered by solar. This… Continue reading Five famous buildings with solar
The value of a well insulated home
While browsing Cleantechnica I found the answer of a key question I have been having ever since writing my Master’s thesis. French houses are leaky ” thermal collanders “ as 20 million accommodations have to be weatherized. Potential savings could be the equivalent of 200 TWh of electricity per annum, knowing that the total electricity… Continue reading The value of a well insulated home
France unveils new efforts to renovate buildings
It had been a long while since my last post on Cleantechies, as I didn’t post during summer. But I am back with a post on a topic close to my heart as my Master’s thesis was on it. The French residential sector could benefit immensely from energy efficiency efforts and it seems the current… Continue reading France unveils new efforts to renovate buildings
