I suggest you read the book Peak Oil, Climate Change and All That Jazz, by Louis Arnoux

This will give you a good look at the future of solar which can easily provide all the heating, cooling and on demand electricity (even at night) needed without a battery storage. Instead store solar energy as compressed air.
For transportation look up the Progressive Automotive X Prize competition and the 136 roadworthy vehicles that get 100 mpg. Included is MDI/Zero Pollution Motors running a compressed air motor car.

Between solar and wind power world energy can be 100%.
5% tops. Cars don’t run on it. Planes and trains don’t run on it. The most you can get out of solar today is about 5 Watts per square foot for a few hours per day. That means per day you can get 100 BTU per square foot per day. That means it will take about 1000 sunny days to produce the energy of one gallon of gasoline per square foot. An entire acre would only produce the energy of 40 Gallons of gasoline in a day.
Solar is great for heating to a point but it is not the answer.
100%
It is possible to fit 1,858,560 solar modules in a square mile. An area of solar panels 102 miles to a side would be sufficient to generate 4,000,000,000,000 kWh of electricity or enough to power the entire US. –Source The Solar Living Source Book by John Schaeffer
I can’t find the link that states that the amount of sunlight that hits the Earth in like 1 hour is enough to power the planet for a year…
