Tonight at 20:30, all over the world, individuals, companies, government organisations, and possibly even Her Majesty the Queen, will switch off their lights.
This symbolic gesture marks Earth Hour, initiated by the World Wildlife Fund (WWF) in 2007 as a lights-off event to raise awareness of climate change.
162 countries and territories worldwide now take part in Earth Hour.
You can get involved and help to raise awareness about climate change by switching off your lights at 20:30 local time for one hour. You can share your thoughts on the climate change challenge on Twitter using #YourPower.
I recently came across the story of one country, Costa Rica, whose citizens are prepared to go much further in the battle against climate change. Since the beginning of the year, Costa Rica has avoided the use of fossil fuels altogether.
The Costa Rican government recently issued a press release announcing that during the first quarter of 2015, they relied on renewables for 100 per cent of their power generation.
Whether we like it or not, energy from fossil fuels is going to be needed for around another two generations.
It is not a comforting thought to think that our descendants born in 30 or 40 years time may be left with the legacy of not acting now to mitigate the effects of climate change.
We need to press ahead with building capacity for renewable energy. There’s also no time to waste to implement carbon capture and storage (CCS) technology for the hundreds of fossil fuel power stations that will still need to be constructed in the meantime. Without CCS, it is unlikely we’ll get anywhere near the Kyoto targets.
In some parts of the world, at certain times of the day, there’s just too much energy – and nowhere for it to go. It’s a problem more and more energy suppliers are likely to experience.
The problem is particularly acute in places like Hawaii. With no natural fossil fuels it has traditionally shipped oil and coal thousands of miles by sea at great cost. The result for Hawaii’s residents are electricity bills three times higher than mainland USA.
There is potential in most things, even the waste that disappears down the toilet bowl.
But along with the waste, there’s the water we use to flush it away. Before water arrives in the toilet bowl it takes energy to process it. And once it disappears down the drains it takes more energy to re-process again. It’s something we pay for as part of our everyday utility bills.
Turning the potential of toilet water into a source of renewable energy, and a way to reduce bills, sounds like a good idea to me.
Do you find it hard to explain what you do and why it’s important? It’s a common problem and even the best communicators struggle to convey the science, complexity, scale and even the products we make – industrial or for consumers.
However, it was great to see a project this week in Malaysia where students from the Universiti Teknologi Malaysia took a mobile mini biodiesel reactor into the streets to help the general public’s understanding of biodiesel. It’s the type of initiative that fits perfectly with the ChemEng365 campaign.
