It will be a mix and realistically the grid will have to be broken up into smaller parts. We already have apartment blocks in Australia who run their own electric grids. Infrastructure will have to change and Europe has already been doing this it is why the European car manufacturers feel confident to move away from petrol cars. Asia is also starting to make changes which will lead to Asian car manufacturers heading in this direction. There is no stopping the change and it is not just about climate change we have all become more aware of the hazards of air pollution. The UN has declared it the great health emergency of our era. If your country is not preparing for electric cars you'll end up like Cuba trying to keep alive old cars with a mish mash of parts you can find which I guess for car enthusiasts would be the dream 😂 That sounds like a lot of unspecific handwaving.

And you certainly can't use gas, oil or coal. So what is left? Hank At the current time generation is actually readily available to support many new cars in California than are currently on the road. The grid actually isn't taxed all that hard in California outside of the evening hours when people tend to run air conditioners, cook dinner, turn on lights, etc. During the day -especially when the sun is shining - power is so plentiful in California that wholesale prices actually turn negative at times and more so every day due to "excess" solar on the grid. This provides an opportunity to charge cars at very low prices. Same overnight when baseload generation plants are idling. With the right software and pricing signals, it is possible to use the system that we have much more efficiently and charge many more cars without building any infrastructure other than creating charging terminals and more energy distribution infrastructure. EVs actually excite the California utilities a lot as they can make money building out this new infrastructure for car charging. The utilities think EVs are as good or even better than air conditioning. This is especially true since the utilities here don't make any money from power sales directly. 1 hour ago, ilikeanswers said: We already have apartment blocks in Australia who run their own electric grids. Most of these I am sure aren't really running an independent grid. I would bet that this is more about making solar generation subsidies available to customers that live in multi family housing rather than running their own grid. Almost all of the benefits of solar subsidies have benefits to date have benefited single family homeowners and commercial enterprises. Going truly off grid really isn't worth it and really adds to the cost except in special situations. For example, I know of some work in Western Australia where the utilities are taking down power lines and substituting local generation to reduce fire risk associated with downed power lines in rural areas. Same in California. Maybe this is also happening where you are as well given the fire risks that exist pretty much in all of Australia. 2 hours ago, ilikeanswers said: If your country is not preparing for electric cars you'll end up like Cuba trying to keep alive old cars with a mish mash of parts you can find which I guess for car enthusiasts would be the dream I know several people here have both electric cars and Baja "war wagons" for surfing and camping. I am not going to switch to a pure EV as I only have a single vehicle and want the flexibility for traveling in less developed areas of Mexico. Even a Tesla with a100kWh battery would be challenged driving to Cabo from San Diego efficiently for the foreseeable future. Driving a Tesla might also attract some potential unwanted attention even though the preferred vehicles of the "narcos" are large 4-door trucks.

Solar panels are filled with toxic electronics, and windmills are huge. This is true at the current Right now the infrastructure for recycling solar panels is very immature and expensive. The same is true of lithium ion and some other types of batteries. Many of these chemical batteries are actually a bit tougher to recycle than solar panels. The hope is that these industries will develop over time and solve the recycling problem as the demand grows. Only time will tell if this is true. 1 Link to comment Share on other sites More sharing options...

There has been a push to look into decentralising the power gird because of black out issues like in South Australia. They say microgrids will make it easier to manage electricity in our cities especially if we want to use renewables as our base load. Link to comment Share on other sites More sharing options...

Hopefully at some point this will actually turn into vehicles that can be produced and sold at a profit. Perhaps our friend in Sweden has the same problem that many in California also have. More than 10% of car sales here are now EVs and plugins. However, the vast majority of these sales go to higher income people that live in single family dwellings. In CA, those living in multi-family housing don't typically have access to charging infrastructure at home. Additionally limited work place charging exists. which makes EVs impractical for many. The real question in California is who is going to pay for all the new charging infrastructure mandated by policy? My guess is our state's highest in the nation tax and utility bills are going higher still. 23 minutes ago, ldubs said: Could build more dams. Should build more dams.

It would be easy - from an engineering perspective - to create pumped hydro projects in the Sierras that would provide storage for all the increasing amounts of solar energy generated that has nowhere to go.

Not the way I choose to live but to each his own. This is absolutely true. The state has been making gas plants uneconomic by having rules/laws that prefer renewable resources over traditional powerplants. The state regulators also "cheated" with fake assumptions around a topic called "resource adequacy" which is supposed to ensure that you have adequate margins to meet the worst case demand. The notion of demand response (i.e., turn off the air conditioner) is now baked into the model. They also have some assumptions about how much renewables will be available which can change with the weather. Unfortunately the model is wrong and the Grid Operator told the utilities to cut power to 100's of thousands of customers. Sometimes progressive dreams don't work out as planned. I personally am hoping we have more outages to help wake our politicians up from their utopian dreams. 3 Link to comment Share on other sites More sharing options...

I would love to see information documenting that. Volkswagen certainly needed prodding as they are currently installing an EV charging network in the US for lying about diesel emissions in government testing. Regardless of infrastructure, Europe has some disadvantages with respect to how people live that makes charging more difficult. Many people live in flats compared at least to the US and as a result home charging can be an issue and this creates complicated, expensive retrofit projects. It will come, it's just time consuming and expensive. Same is true on the work front. Here is a chart showing how people live https://ec.europa.eu/eurostat/statistics-explained/index.php?title=File:Distribution_of_population_by_dwelling_type,_2018_(%)_SILC20.png BTW - at least in CA many public EV chargers are available even if the tend to be scattered about at shopping malls, restaurants, etc. Most charging stations aren't well branded or visible. Most people just have an app on their phone to find them. I assume the people using these are mostly travelers or people needing a quick charge to get home as everyone I know simply charges at home. Here is a popular web site for looking up charger locations in the US - https://pluginamerica.org/ if you ever decide to visit her in the future.

It's actually better to solve it at the overall grid level as the network effects of sharing resources are better and implementing resources grid side is way cheaper. What is driving a lot of microgrid activities in California is a desire of companies/developers to keep the renewable subsidies alive by providing a new service to sell. Even our "woke" regulators are suspicious of the microgrid claims and have so far said no to additional subsidies. Microgrids do make sense where the grid isn't or where utilities spend millions of dollars to serve just a few customers. The options today are really amazing if someone wants to live off the grid while still having all the "normal" convivence associated with on grid living.

The issues with big chunks of the Australian grid going down has really has more to due with policy and political issues than engineering challenges.
