As commented in a recent post on renewable islands, to completely decarbonize islands, it is necessary to use renewables for electricity and heating, together with the electrification of transport. (Actually, electric mobility serves as renewable storage)
By transport I mean electric mobility on land, that is vehicles, rail, buses, but also on the sea. How can we decarbonize sea transport?
No, I’m not proposing getting our hands on the oars or going back to:

I already commented on the self-consumtion regulation in draft in Spain, (basically a retroactive measure to stop any development). The reason behind is the excess of fixed system costs; with decreasing energy consumption, power and energy prices increase in a feedback loop. Blocking self-consumption is an attemp to avoid further grid energy consumption decrease.
As in other countries with similar fixed costs, decreasing demand pushes towards higher energy prices, and taxing self-consumption is seen as a regulatory solution. Apparently off-grid is becoming already a cheaper option. As it is not the best solution for the system as a whole, an intermediate solution could be the following: Sigue leyendo →
The key was and is to use inexpensive harware. With servers, rapid obsolescence meant they wouldn’t need to repair the PCs used for their servers, many of the servers wouldn’t ever work, and the design had to be optimized to work around these failures. Of course now they are interested in the most energy efficient server systems, as that is the main cost for operating data centres, but the cheap and fast concept remains.
While this may look promising, and seem the perfect way to increase renewable penetration, paving the way to a decarbonized energy sector, please stop. …and reconsider if it is the best solution.
Why decarbonize the power sector alone… if we can decarbonize the transportation and the power sector at the same time?
How? Investment in electric vehicles (EVs) must be economically efficient in itself (cheaper than the CO2 emmitting vehicles) so every € invested has already a return via mobility (for the owner/user). This means using the available storage is relatively “free” to the power sector. In my opinion, subsidizing battery storage (gathering dust inside a building) is a stupid idea compared to incentivizing the “transport-sector-decarbonizing-storage” or, to say it other way, batteries-with-wheels. EVs should be incentivized not only by governments trying to reduce the energy sector trade unbalances and reducing CO2 emissions, but also by utilities willing to increase the customer’s bill (an EV customer is billed aprox. a 30% more)
