Absolutely untrue. The problem lies in a short lifespan of infrastructure usually about 20 years for both wind (mainly due to cyclic stresses in turbine structure) and solar (loss of panel efficiency in time). Please do not forget to add all taxes to renewables that are thrown on fosils. Only hydroelectric is economically viable - the rest would never ever exist if not for humongous state subsidies on all phases of construction, maintenance, utilization and decommissioning. Maybe apart from some very remote areas where you cannot easily get fossil fuel regularly. Hopefully latest good advances in photovoltaic technology will allow for economical use in areas close to equator.

Please note this is in perspective of electric car powering. Solar thermal and geothermal (for heating and cooling) can be economical provided right external conditions are present.

Add efficient pricing of externalities (which one always should) and it might not be so straight forward.

While we don't know what the efficient price is (because we don't yet know the extent of future global warming and even if we did, it'd not be easy to determine the added costs of it), we can try to find a best estimate.

Why not just do something practical like Brazil and use ethanol or plant based fuel. You don't have to be a real trigonometry tutor to figure that out.

Well, looks like another milestone passed for electric race cars. Now one has the world record on the Nordschleife of the Nürnburgring.

Well, outside competitions at least. In 1983, a number of speed races were held on the 'Ring, with the best cars and drivers of their age duking it out, some finishing up to half a minute faster than the cars that drive there today. The records set that year are still standing. For some reason, F1 cars haven't driven there.

Anyway, enough talk, more video:

The goverment of that particular nation should incourage people on buying these electric cars providing the buyers with some sort of benefits. For example in Norway electric cars are excluded from value added taxes, including no purchase and import taxes, can use toll roads and bus lanes for free as well as park for free in city centers, the goverment of Norway made electric cars irresistable to people others should take note.

Off course he is not greedy and his company is overvalued and overhyped. He had never ever reached a profitable month, Tesla is hype scam. That is why he needs his workers to work in bad conditions. So he can fulfill his wet dreams and parazit on the society along the way.

I see. "Are you a rich fuk that can afford 100k€ car? Oh, yeah, here, have some benefits!" is the new rhetoric of socialists. The truth at last, that these commies were never about the working class, but their own rich fat pockets is finally coming to the light...

Except it is absolutely useless for anything else. Would rather buy a scooter, which is ten times cheaper and has the same advantages and benefits... Even more, because it is smaller, it can avoid traffic jams even where there is no bus lane.

Maybe that is why the 8 years old Polish tricycle-thingy has closed down its business in 2015... http://www.revoltev.com/ And that Swedish thingy is rarer than Teslas on European roads...

Only if we stop the fearmongering and start building Fast Breeder Reactors right now or in 10 years time scale. Problem is a low percentage of fissile Uranium in the Uranium ore, only 0,7%. Fission reactors work with uranium oxide enriched(of U235 isotope, the most common isotope is U238) to 2,5-5%. Fast breeders are reactors with enrichment of the ore >90%, use molten salt as a coolant and have walls out of U238 that they transmutate to PU239. Because there is literally 100 times more U238 than U235 and the cross-section(probability) of fission by fast neutrons is low(something like 100x lower) compared to the cross-section, they can produce more fuel than what they consume.
Here is the estimated supply of uranium

EROEI of solar 6, EROEI of wind 18, EROEI of oil 20, EROEI of coal 80. Even though:
https://ourfiniteworld.com/2016/12/2...re-misleading/
They are still far from competitive to oil and coal, and they are subsidized...
Plus, they have a million problems.
In the industrial scale, you can not really substitute oil and the industrial oil use makes up 20% of CO2 emissions. The household emissions make up only 6% of CO2 emissions. With clean energy you won't certainly ever replace oil in transportation sector(because the biggest CO2 emitters are ships and planes), which makes up of 22% of CO2 emissions and you can only slightly cut CO2 emissions of electricity production(only by the household electricity consumption). Sources for these numbers are here http://whatsyourimpact.org/greenhous...xide-emissions It is because of the electrical grid and its stability. There is a problem with solar and wind power and it is that power from it fluctuates heavily and it is very unpredictable. You can read about the fluctuation here http://iopscience.iop.org/article/10...30/18/6/063027 or less scientifically here(this webpage also describes how they try to predict the fluctuations) https://www.siemens.com/innovation/e...-networks.html or here(this article discusses the economic impact of "green" energy) https://oneinabillionblog.com/energy...es-in-germany/ or if you search for it on the internet literally almost everywhere, since it is a big issue.
Long story short - the grid stability is a big issue. The electricity grid does not cope easily with fluctuations and they have to be compensated somehow. The only two ways how to do this are by pumping hydro power stations or by fossil fuel power stations. The latter is economically more feasible and more efficient, while the former is expensive as hell, not very efficient, needs a huge landwork that comes hand in hand with damage on local countryside and ecosystem and so on... That is why the most used method is to regulate using coal. This led to what is known as "german paradox" - where the percentage of "clean" energy out of the total energy generated is rising, but the carbon emissions are rising as well. https://www.cleanenergywire.org/news...-coal-use-drop

There were studies about the use of electric cars as energy storage, but that wet dream has a few catches. First is, that it would mean that all of us are going to give up our freedom and commit to North Korea-like dictatorship and resource-planning when the government is forcing us to limit usage of our(also, this has to be enforced globally, not only in Europe and the US and China, the biggest world CO2 emittor gets a free pass... That would also mean to stop development of the developing countries and conserving third world into the current state forever) cars and have them connected to the grid for some time a day because of uncertain dystopic future predictions that we can not be sure if they are right and we can not be sure we will even stop by this action(since the CO2 levels may be rising in the current tempo not only because of the human activity, but because of the positive feedback loop only started by human activity, but caused only by melting of the ice and ocean CO2 cycle - CO2 gets absorbed in the oceans, the plankton metabolises it, plankton dies, the CO2 gets trapped in the depth of the ocean and below the ice, then when the temperature rises, the ice melts releasing the trapped CO2 causing more temperature rise and more ice melting etc. etc.). Plus, the batteries have huge catastrophic environmental impact when manufactured and when they end their lifecycle.

Elon Musk Just Revealed a Major Tesla Model 3 Event Coming Soon

By Mike Brown 9h ago

The wait is almost over. Tesla CEO Elon Musk revealed on his Twitter page Sunday evening that the Model 3 has passed all regulatory requirements “two weeks ahead of schedule,” and the first production car should arrive shortly. To celebrate, Musk has announced possibly the most hotly anticipated event in the Model 3’s journey: the launch party.

The Model 3 is an important moment for Tesla. The entry-level sedan will start at $35,000, far cheaper than the company’s current cheapest car, the $68,000 Model S. The release opens Tesla up to a far wider market, and demand is expected to be high for a vehicle made by a company that, until now, has only made electric vehicles priced at a premium.

After the U.S. government tax incentive of $7,500 that will be available to potential buyers, the Model 3 will actually cost nearly $28,0000 vice $35,0000.

1.) There are studies that show the amount of CO2 produced in making the batteries that go into these cars offsets the CO2 saved by not burning gasoline. Popular Mechanics recently estimated 2.5 years required to offset the CO2 emissions of a gasoline-powered car: http://www.popularmechanics.com/cars...udy-fake-news/. Of course, this value can go up or down, depending on the size of the EV and conventional vehicle being displaced, and the amount of driving.

2.) EVs today are impractical since they will rely mostly on fossil fuels indirectly (so they will contribute CO2 emissions themselves). You'll increase the load by charging your EV, which is likely being met by natural gas or coal. You also have the losses incurred in transmission and distribution to contend with.

Once/if your power generation is coming from renewables, then it may make sense (if you displace 2.5 years worth of driving to offset the CO2 produced from the battries' manufacture).

1. You assume the electricity comes from fossil fuels and the renewables are something that is coming later. Not so at all in many places. Hydro is huge in some parts and has been for decades & decades. Nuclear is also low in CO2. Sure, in Saudi it's all about the oil. But much of the world isn't swimming in oil (or coal), never have been.

2. A good oil power plant can both reach efficiency that a car engine can't and can have exhaust control like a car can't. So even with a fossil fuel based power grid, you can get less harmful exhausts.

That said, Saudi and it's neighbours are amazing places for renewables. Reliable solar ftw!
