I like electric cars. The environmental friendliness of the electric car is its huge advantage. Another advantage is that the car is very quiet and does not require large maintenance costs. But there are big downsides. The new car is quite expensive. And even if you have already bought such a car, you need to charge it somewhere. And it seems to me that this is the biggest problem, because we do not have a well-developed infrastructure of charging stations. I think over time it will all improve and develop, but personally I will wait with such a purchase.
All of this "clean / green energy" simply isn't there yet. From both an infrastructure and / or technology standpoint. Until electric cars can compete with gas and diesel powered vehicles in a load / pulling power, (semi truck transportation), and a distance before recharging, and most importantly,
TIME to recharge, they are not going to be acceptable replacements. About all they amount to presently, is an impressive toy for the progressive movement. That make them feel good about themselves, and what they want.
It's no different with wind and solar replacing fossil fuel for home and industrial use. We saw a glimpse of that reality with the all but total failure of the Texas power grid this past Winter. The fact of the matter is, the wind doesn't blow all the time, and the Sun doesn't shine all the time. And battery technology is nowhere near where it needs to be, in order to make up for the rest through electrical storage.
Bill Gates, (love him or hate him), commissioned a study on battery power. It found that all of the batteries presently existing on the planet today fully charged, would only supply enough electricity to last the world 7 minutes. That is nowhere near enough to compensate for the energy that wind and solar cannot provide.
Solar panel technology has improved to around 90% to 95%. Meaning solar panels are about as developed as they can be. Now, or in the future. Wind has it's own issues and problems in regards to cost, maintenance, as well as longevity. In order for it to either break even, or else pay off. Problems with delamination and damage of the fiberglass blades is occurring much sooner, and is far worse than was originally anticipated. This is becoming a massively expensive problem. And most importantly, until the entire world, (think China), is on the exact same page as we are in all of this, none of it is going to matter in the least. At this point all we're doing is blowing smoke up each others collective asses.
