This article is a slightly re-written assignment I had to write for my Certficate in Sustainable Energy Solutions at Pinchot University. Hope you will like it !
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.
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.
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.
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.
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.
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.
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
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
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
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
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
