Tomorrow’s energies: clean, renewable and green !

Tomorrow’s energies: clean, renewable and green !


For several centuries we have been using our Planet’s resources without giving a second thought about their limited quantity.  Even though the stock is diminishing and our needs are increasing we still carry on using it in spite of it forthcoming end. To answer this energy demand, which can only rise due to both our population and life style increase, it has become more than urgent, and in the long term vital, to be able to efficiently exploit/collect new energy sources as well as to store them efficiently.  

At this stage it is also important to rate the environmental impact of what we produce and what we buy.  We must be eco-responsible and make energy-related choices which in the end tend to preserve our environment. Let’s never forget that the least polluting energy is the one we do not useUntil we can benefit from the technological breakthroughs and the energetic solutions under study, we can always start with reducing our energy consumption by changing a few habits to our behaviour in a daily base.  For example, reduce the use of standby electric appliances or simply switch them off, regularly defrost the freezer, do not leave the light on when not needed, walk or ride short distances, choose public transport or car-sharing for longer ones,   or my electric car!

Let’s remember that as an answer to the first oil crisis (1973), which abruptly put an end to the industrialized countries’ carefree attitude toward energy, the French government imposed strict rules: 1) the maximum speed was reduced to 90km/h on main roads and 130 km/h on motorways, 2) air links on the French territory were reduced, 3) no display window lighting, no illuminated advertising, no lighting for monuments and no lights in the offices between 22h and 7h…and even 4) TV programs ended at 23h;  the purpose of these rules was to stop wasting energy with a lot of simple daily actions that each French citizen must concerned with. 

We should remember that that only 25% of our CO2 emissions come from our means of transport, but it is striking to notice that more than 50% of our individual CO2 emissions come from consumer goods (production, transportation, storage, recycling, waste collection and disposal).

It is our responsibility  to take part in this energy change and we must realized that our behaviour will impact technological and scientific innovations so that tomorrow we can benefit from new viable energies while preserving our Planet and thinking of what we are leaving behind for our children.
