Electricity usage has been falling in the UK since 2002. Meanwhile, the grid has been getting cleaner by the year.

Wind, solar and hydro made up 27.5% of the UKs energy mix in 2020.

Go back 10 years to 2010 and that figure was only 6%.

You can take a deeper dive into the data by exploring the UK Electric Insights – provided by Drax.

The Dumbest Experiment in Human History

We’re using less energy and burning fewer fossil fuels, which is definitely a good thing! Every kilowatt-hour (kWh) of clean, renewable energy generated is a step in the right direction and a step away from what Elon Musk coined “the dumbest experiment in human history“.

Even today, we still burn a lot of fossil fuels and other carbon emitters. Given climate change is now more pressing than ever, the drive for efficiency has never been more important.

So the scene is set: every kWh of consumption we can avoid is positive for the planet.

Energy Labels

From March 2021, you’ll start to see changes to appliance energy efficiency rating labels in the UK – and also across Europe. The old label will be phased out, being replaced with a new simpler one, aiming to promote higher standards of efficiency.

Each appliance type has its own label with additional info. For example, the TV label includes screen size, and the energy consumption of HDR mode. The label for fridges has a decibel rating (so you can compare noise levels) as well as the storage capacity.

The most noticeable difference is in the efficiency ratings. These have been simplified to an A to G scale. Before the range was A+++ to G-, which added complexity – especially as not all the labels were displayed on the chart!

New UK Energy Label — The new UK energy label

The new A to G label also has significantly stricter criteria – as it should if we’re to achieve our climate targets!

With every year, technology develops and efficiency improves – appliances need less power to do the same thing. As such we need to hold appliances to a higher standard. It’s worth remembering, this isn’t only good for the planet, it’s also good for your pocket. Buying a more efficient device which uses less energy will also save you money on energy bills!

If you bought a fridge in 2019 with an A+++ rating, that’d now be rated a B or C in the 2021 label.

If everyone stopped buying G rated products, manufacturers would stop making them. If more people buy A rated product, manufactures will put more research and development into making their products even more efficient – maybe forcing another label change! 😂

Reduce, Reuse, Repair, Repurpose, Recycle, Replace

You can help by knowing and using your “Rs”!

Reduce usage where you can – turn off the TV instead of leaving it in standby mode
Reuse your existing fridge, TV or washing machine – if you don’t need a new one, don’t buy one!
Repair what you’ve got before looking for something new
Recycle or Repurpose the appliance you have so it can have a second life – upcycle where you can
Replace it with an energy efficient one – and only if you can’t do the other “Rs”

So next time you need a new appliance, check the “Rs” to see if you really do need a new one, and if you do, look out for the new energy efficiency label and use it to help you pick the most efficient one 🙂

One of the best places to put a telescope is in the Atacama Desert, which is on the boarder of Chile and Peru – currently there are around 20 telescopes (both radio and optical) functioning in the area.

The Alma telescope

In the last few days, the world’s largest radio telescope, the Alma telescope, has began to function. Currently the telescope is made up of around 20 massive antenna dishes, which work in harmony to produce amazingly detailed pictures of outer space.

The project has input from all around the world, with Europe, North America, East Asia and the Republic of Chile forming a partnership, all doing their bit to add more antenna dishes and improve the telescope.

When the project is completed, (hopefully within the next 20 years if all goes to plan) the telescope will have a whopping 66 dishes at its disposal, all of which it can use to gaze at the stars in fantastic detail!

Why the Atacama Desert?

You are probably wondering why the Atacama Desert is such a hotspot for telescope activity. Well there are a number of reasons, but the main ones are that it has clear skies almost all the time, in addition to very dry air – meaning that its hard for humans to breath there due to low oxygen levels, but for the telescopes, that means very little interference from anything in the space above.

Furthermore, the desert has many high flat areas, meaning that telescopes can be closer to the atmosphere, meaning even less interference. In addition to this, because the Atacama is a desert, it has virtually no light pollution. Basically it is an astronomer’s dream location!

Is it working?

The project has only been live for less than a week now, but already some stunning high detailed pictures of space area already beginning to emerge. Below is one of these great pictures:

Because the light we can see here on earth is often millions, if not billions of years old, we are able to see into the past when looking up at the sky, using super powerful telescopes like the Alma one.

Scientists believe that we will be able to see events that happened just 400 million years after the big bang, due to the light delay, hence enabling us to understand better than ever before the formation of the early universe.

The Alma telescope is just one small cog in our planets fascinating scientific road of discovery, however one thing’s for sure: this ‘small cog’ should be able to help us understand a lot more about the universe than ever before!
