Define clean energy....How can our solar and wind power store it's energy? ...and if it can't, there needs to be base load support from other sources....Germany's spent a lot of money on solar and wind, but their CO₂ emissions have continued to increase, their particulate emissions have increased....What is the goal here? Why do people keep saying this is working when it's not?

"Had They Bet On Nuclear, Not Renewables, Germany & California Would Already Have 100% Clean Power"

"Had California and Germany invested $680 billion into new nuclear power plants instead of renewables like solar and wind farms, the two would already be generating 100% or more of their electricity from clean (low-emissions) energy sources, according to a new analysis by Environmental Progress.

The analysis comes the day before California plays host to a “Global Climate Action Summit,” which makes no mention of nuclear, despite it being the largest source of clean energy in the U.S. and Europe.

Here are the two main findings from EP's analysis:

• Had Germany spent $580 billion on nuclear instead of renewables, it would have had enough energy to both replace all fossil fuels and biomass in its electricity sector and replace all of the petroleum it uses for cars and light trucks.

• Had California spent an estimated $100 billion on nuclear instead of on wind and solar, it would have had enough energy to replace all fossil fuels in its in-state electricity mix."....

Ain't it the truth...

I agree with SE. I do wish they would commit to "zero carbon" electricity, instead of "renewable" electricity. Natural gas is cleaner than coal, of course, but it is still a combustion process generating carbon dioxide.

Ok I decided to look at one of these cities at random...Denton, Texas

So they're committed to 100% clean energy by 2020...less than 2 years...

Here's the first thing I found...

....and then this...

You can sign up for using 100% solar and wind power for an additional $5 a month....they qualify this by saying

"DME will use the state's wholesale electric market to acquire renewable energy credits on behalf of GreenSense customers. "

Do I really get 100% green renewable energy?

"Customers choosing GreenSense will not have electricity from a specific renewable generating facility delivered directly to their house. Instead, they are supporting generators of cleaner energy that provide electricity to the state’s power grid. DME will ensure that electricity equal to our GreenSense customer's annual electricity usage is delivered to the grid, replacing the non-green power that would have otherwise been purchased. "

Total BS....
