Here is something intelligent : utilities offering LED bulbs to decrease your energy consumption. As an example of this I received this month a FREE super efficient bulb. Thanks Seattle City Light for making my household and thousands of others more efficient !
Versailles, le Louvre and countless châteaux… These monuments must be hard to heat and must be hard to lit. But what if a British castle showed the way to solve these problems ?
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.
This was a major setback for me last week, US greenhouse gases emissions related to energy rose two percent in 2013 compared to 2012. To the US EIA this is due to ” a small increase in coal consumption in the electric power sector. “
” Coal has regained some market share from natural gas since a low in April 2012 “ This is explained by decreased coal prices and rising natural gas prices as the Los Angeles Times reported.
Overall, US emissions are still around ten percent lower than in 2005. President Obama goal’s is to have 17 percent lower emissions in 2020.
The capital city of Argentina, Buenos Aires, have switched its 125,000 streetlights to LED. This will cut energy consumption by half and will last five times longer. With 13 million inhabitants, it is the second largest city in South America.
To TreeHugger : ” That’s just one city. It’s estimated that if cities around the world made a switch to LED tech like Buenos Aires, savings would add up to €130 billion ($180 billion) in reduced energy costs each year. “
” It would also prevent 670 million tons of CO2 from being released into the atmosphere each year. Not bad for streetlamps! ” This just shows that energy efficiency works.
My time out for the past two weeks in southern France was the occasion for me to think a bit about energy and environmental issues as I was experiencing stuff I have been writing about on this blog.
Exemplifying with day-to-day and real-life examples is a fantastic opportunity to see how stuff just works. From LED lights to trees and from solar to building insulation, these are topics that are very general.
I will share these thoughts with you in today’s article and I hope you will find them enlightening. I look forward to reading your thoughts.
According to a study carried out in the United States by the local Department of Energy (DOE), the 49 million LED light bulbs already installed helped save a massive $675 million (over 500 million euros) in a single year.
But wait, there is more as if all light bulbs in the United States were replaced by such bulbs, the potential savings could be the absolutely huge amount of $37 billion (27 billion euros) per year !
This would half the amount of energy consumed for lightning in the US. Now let’s imagine what this would lead in terms of decreased greenhouse gases emissions in the United States alone.
Do you know Kickstarter, the world’s largest funding platform more used to fund video games and other similar projects ? Well, one of its recent successes is the Nanolight, perhaps the world’s most efficient light bulb.
Only consuming 12 W to offer the light of the traditional 100 W incandescent bulb, the Nanolight was developed by three students from the University of Toronto, Canada thanks to the +$240,000 they gathered (they wanted to gather $20,000).
This light bulb has many other great features including omnidirectional light, full brightness as soon as it is switched on and so on.
For the second part of this series – the first one was on heating – we are having a look at electricity consumption of households and the various ways we can decrease it.
This will enable you to have lower energy bills – always a good thing with the hard times we have – to cut your carbon dioxide emissions and thus enable you to have a more sustainable lifestyle.
From your lightning to the various appliances around you, the opportunities for savings are numerous and this post propose you a selection of three.
Incandescent light bulbs are a relic of the past, a vastly inefficient past. Modern alternatives like CFLs and LEDs consume five to ten times less energy. For these reasons, the European Union or Australia have already phased them out. More countries will be doing the same, namingly the United States and China. The latter will … Read more
Now LEDs are slowly reaching the markets. Consuming up to half the energy of CFLs they come in all shapes and colors. Even if they are still very expensive, they can last 35,000 hours and can lead to substantial savings over their lifetime.
So if further to my post on decreasing your electricity use you are switching off your incandescents, why not choosing directly LEDs ? You will find below a list of the main advantages.
