Electricity is not a source of emissions during use, but ... how does it come from, and how will electricity be produced? Each country with large differences in proportion and type of plant produces electricity from:
• TRADITIONAL POWER PLANTS: Electricity produced by nuclear power plants (without direct emissions but ... and in Italy, we are at 0), from hydroelectric power plants, the only ones without emissions (but they will be few). For the CARBON, GAS, TURBOGAS ... IDROCARBURY – DIESEL plants, generally derived from oil, though differently, are resources we know are decreasing, and whose use, even with filtration systems, results in unavoidable emissions that are all 'Evidence of all.
• RENEWABLE POWER PLANTS: wind, photovoltaic, solar thermodynamics. For each of these systems for which it took decades to reach current production quotas of about 20% of the total, with objective limits the plants cannot be installed anywhere and therefore achievable, and the desired growth will still take decades;
As each country, where it is located, the natural resources available, for policies and energy choices implemented in the past few decades, has its own characteristics. It's good to remember, for example, that in the Netherlands with thousands of wind turbines installed in the sea, for a few days, even there was a surplus with a negative payment (-100 euro x MW) of the energy invested in the network; In Germany, for a day, 61% of the production has been achieved with wind turbines ... well-equipped and equipped nations, but always ready to use the LEAD AND OTHER ACTIVITIES CENTRAL NUCLEAR ... that for decades, Italy, also gaining its energy produced, contributed to paying the cost of the plant.
Even with all the related issues, it is desirable that "free" and "clean" solar energy should grow and expand with large, huge financial investments, but taking into account the location of wind power ... (OFFSHORE IN SEA) and photovoltaic actually on marginal land or on sheds, which strangely, though strongly incentivized by incentives, did not adhere to the various energy accounts which, however, "weigh" on the pockets of all citizens.
Returning to a situation that for 20-30 years will see us compulsory in the current situation (or with micro-variations) reiterating each nation has its different realities ... in general, an electric car does not originate directly from emissions but:
ELECTRICITY IS PRODUCED WITH APPARATUS, PLANTS, E-MOTORS FOR WHICH ... EMISSIONS AND POLLUTION ARE THERE, AND THERE WILL COME!!!. THE PROBLEM IS ONLY POSTED BY OTHER PARTS.
For several reasons and for some situations it is definitely a solution that has, and will have its (small) space in the cities but, unless unlikely free-energy inventions (the known laws of physics, for now, do not admit miracles) at least for over the next 30 to 40 years, it will not be able to spread as such to be alternative to current systems and thus reduce pollution and exploitation of natural resources that are exhausted.
• New high power conductivity and low loss transmission networks:
• New thousands of large wind power plants, photovoltaic plants of various types;
• New high-capacity batteries, made with available raw materials, of acceptable duration;
• New "ECOnuclear" plants in Italy in 2050 in Italy (possibly in England in 2030) with the experimental evidence of a nuclear fusion plant that, hoping to give positive indications, after another 10-15 years, will be able to start construction of the first "ECOnuclear" power plants, that is, without emissions and without slag.
We hope for these future solutions, but in the meantime, we should set up and try to solve the existing problems.
REFLECTIONS AND SIMPLE ANSWERS QUESTIONS ON ELECTRIC MOBILITY:
ORDER: if seen globally, an electric car has a low performance (from 19 to 36%) because the energy produced at origin, transformed, transported and actually used, is largely lost on the road;
POLLUTION: the unresolved problem is just moved from the city ... to the power plants ... but the air is everywhere ... !!!;
ELECTRICITY: What would happen if the demand for electricity increased (consistently)?
There is not much electricity surplus so there would be a need for other (many) nuclear or traditional power plants ... and how long it will take to build them. and then there would be the problem of electric grids, which should bear much more load:
BATTERIES: Less than unlikely inventions (never lose hope) the batteries, which are the heart of the car, need rare materials so they are unavailable in quantity (there are already problems with lithium availability);
POLLING BATTERIES: Obviously the issues of primary pollution for production and disposal ... maybe we will not have it under the house ... but it's a big deal;
BATTERIES COSTS: current and future (provided the raw material is available) will be subject to a variable that will inevitably increase the demand for more;
RECOVERY TIMES: In addition to the creation an expensive network of distributors, whose inevitably long production times will be over, the super-recharge solution will stress the battery to halve its life ... (costs !!!!);
WARNING COLONNES: to a distributed network of columns, certainly located in the current service stations, it will have to encounter a problem with home installation (in the cottage obviously no problem) but in the case of common condominium motorbikes it is unlikely that there will be agreements on costs, spaces to be used, priority of use ... !!!,
AUTONOMY: For now, it is known that autonomy is relative, 50-100-150 km so or is a city car and it's fine, or it's a supercar (300 km), however, destined for a few;
COSTS: high direct and indirect, which, with a series of limitations, make it destined for a few who can afford two-third cars in the garage;
ELECTROMAGNETISM: Certainly a strong increase in the energy transported by the networks from one side to the other would have some influence. It is about existing issues with the cellular energy micro emission ... to figure with a greatly increased "circulation" of enormous electricity. Electrosmog exists and is well-known.
PRACTICAL AND UNCONTRACTING CONSIDERATIONS: For Italy, but basically for all countries, it is necessary to imagine people who have to move or tourists from northern Europe who take 4-5 days (minimum) to go to the places of Southern Italy as many on the return ... nice vacation spent recharging the batteries..
The clean and diffused electricity production time horizon is very far, so without focusing on analysis and decimals, it is inevitable that at least for the next 30 years, electric power will, at best, have a diffusion limited, up to 10% (with 1000 upstream problems to solve) ... and maybe 20% (with 1000x1000 obstacles).
THE BEAUTIFUL ELECTRIC MOBILITY IS A LIMITED SOLUTION
RESERVED TO A FEW AND PRINCIPALLY TO BE USED IN THE CITIES.
