Understanding fully today's Energy Problem
& What You can do to about it.

x July 2021 – 4 min read

At Wise, our goal is to build concrete solutions to help anyone accelerate the sustainable energy transition.
The first step before bringing up these solutions is to draw very clearly the current diagnosis of the Energy challenges.

Thanks to the vast amount of scientific papers, researches and articles publicly available, we have been able to report and track precisely the Greenhouse Gas emissions (GHG) caused by our Energy usage since the last decades.

"Energy", this is word we talk about and that we hear everywhere in the news. But what does it mean exactly? And what is the difference with electricity?

Energy 💪 Vs. Electricity ⚡️

💪The classic scientific definition of the Energy is literally "the ability to do a given work" such as to move an object (or a mass) by the application of a force.

What is important here is to understand that the Energy is in the heart of a large amount of our everyday activity (eg: the heat that is generated when you turn on your gas cooker, the movement force you get when pressing on your car gas steer).

The main unit used is the Joules

+ concrete examples and % (heat, etc.) + carbon intensity by source


⚡️ On the other hand, the Electricity is a more restrictive definition of a natural phenomena: the flow of charges or the movement of electrons - the smallest particle of atoms that exist.
These are positively or negatively charged and as 2 magnets that can't resist to each other, charges move in a direction as to neutralize each other. This is creating the electrical field that can create the movement of others charges ("or a "work").

The electricty we have at home is coming directly from large transmission lines where the electrical current is huge (x V) as to be able to transport enough electric power to our everyday activty.
The main unit used is a Watt (or 1 Joule per second)

“The straight line” – Energy usage per person per year since 1800 

We are able to have a pretty accurate estimation of the amounf of Energy consummed Per Person on earth since the 1800's.
What is a bit scary is that it is constantly increasing year by year with almost the same rate as a straight graphic line.

Besides, we can look at the source of energy used year by year. We see that while energy produced from a coal is slightly growing, we see that the share of renewable is super tiny, almost "anecdotic" in the energy world mix.

The main reason why is pretty straightforward: we always want more "Comfort" at a faster and faster rate. While the technology exist to "move all these things and services we buy everyday" it is not yet delivered in a scale that allow to keep the same level of comfort as today.



The main solution before talking about switching to non-polluting source for our Energy is then to see how we can reduce our energy and lead to a more modest & humble lifestyle.

Less energy, lower footprint



We cannot emit more than half of what we already consume since 1850" In practice, it is easier to reduce the CO2 emissions from electricity rather than transport, industry and agriculture

Wise to the rescue

Getting the right and clear information about your everyday usage and the carbon intensity is the most crucial part.

Then, you can test our Fusr, the rollable solar panel at home from your garden or window as to see how much Watts you will need to power up your everyday appliances

Eg:
smartphone
laptop
mini-projector
TV -need a larger battery
fridge
washing machine
heat pump

New opportunities to reduce your cabon footprint

Non extensive list:

* Look at your daily appliances, its power intensity and check which ones are crucial in your daily life
* Check your annual electricity look for a place to place solar panels
* switch to energy contract with local certificate (Energy Bolt)

* regarding heat, look for a building that has the highest isolation and insulation score


+ Check when your grid is the least carbon intensive

If replaced with nuclear, it is “only” 10% of the World GDP every 60 years. If our survival is at stake, there is room for négociations

For wind and solar it would be 20 times more, so 2 to 4 years of world GDP, every 20 years
