There's always the sun

It is known to everybody. Questa è la terra del sole! This is the land of sun, as an old song says.

And sun, with wind and water, has allowed Italy to reach a good percentage of renewable energy production.

In total 13,6% was deriving from hydroelectric and 10% from Geothermal, Photovoltaic and Wind.

 

 

The Photovoltaic percentage is growing and, even though I always thought this was not going to be an option for the production of energy, it looks like I was wrong. The fact is that I grew up with some prejudices.

1) a sustainable technology is the one that does not need financial help

2) a good energy source is what is available when you need it

3) a good energy source can be stored

In reality photovoltaic is not ticking any of these boxes.

 

The first one is probably the quicker to achieve but mainly because the oil extraction is becoming more expensive and less efficient, the oil price is leveled relatively high and the solar cells are produced in a low cost country that, maybe, is giving some help to become the main (I wanted to say the sole) manufactorer.

But who cares... Machiavelli said "the end justifies the means" and our target is to increase the renewable energy production.

Target achieved.

Now some other challenges open before us.

1) we still need to increase the energy efficiency of our system. Starting from the houses (in western Europe 70% of the buildings are built before 1980) and going to the transports.

2) we need to find a way to store the solar energy.

I know about new batteries for PV being developed.

Is there anybody having some information?

I always thought that fuel cells could have been the solution. Store solar energy by generating Hydrogen. I am probably too optimistic though.

This is the key issue. Solving this limit will further boost the solar generation and will also change completely the energy production strategy. Decentralization. Istead of having power plants serving big areas, we will have local plants serving cities, towns, blocks. Less transport losses. Better control.

Clearly we will not be able to generate this

 

 

 

but it will be sufficient for a more sustainable development.

But then, another big challenge starts.

What are we doing with the current powerplants?

 

We are already facing this as, due to the crisis and to the unexpected quick raise of the renewable, the italian thermal power plants are woriking below the "phisiological level". This level is the one that allows to be repaid whithin the budgeted period and therefore to repay who has financed the structure.

 

Less need, less energy, less money.

 

The solution that has been put forward is simple... Let us put the burden on the enrgy bill as an extra tax. So in our bills we should pay for the Nuclear powerplants that have been discontinued, to sustain the renewable energy and also to sustain the non renewable that have been replaced by the renewable sustained by ourselves. Isn't that silly?

What about turning our life from being oil driven to be electricity driven?

What about replacing the gas burners with heatpumps? What about increase the electric transport?

Maybe someone will tell me "yes, but you have signed contracts saying that you must buy a certain minimum quantity of oil and gas". Maybe. Maybe not. But in this case we need to plan for our future. Possibily more sustainable.

 

Have a nice week end. Hopefully with a lot of sun
