No fuel source will be 100%. It will be a variety of fuel sources.
-windmills
-solar farms (private and public)
-natural gas
-hydro-electric
-hydrogen fuel cells
and finally,
-fossil fuel
In 50 yrs., who knows what will be invented by then.
These threads alway bring back memories of my relatives as a very close great-aunt lived to be 101. She was born in 1900 and I took care of her from when she went into assisted living in 1995 and she passed in 2001.
In Italy, she didn't have electricity as they used oil lamps when she was a small girl. Horses and walking were the mode of travel. Moving to the USA in 1919 was a big eye opener.
As time went on, new things were invented and she was excited about a microwave in the 1970's. Phone service became a lot more reliable along with efficiency's of other products....ice box to refrigerator.... no air to window units to central air conditioning.......single pane windows to double pane windows...etc. etc..... the list goes on and on.
All things will improve and be invented in our lifetime, I find that extremely exciting.
The power of Lithium Ion batteries compared to wet cell (weight and charging rates) is one thing we've seen recently along with anything electronic.
