I don't underestimate tech. I make my living with it. Nevertheless laws of physics don't change. I certainly expect efficiency gains, perhaps even new ways of harnessing and storing power. Even so, it will take land mass for renewables and significant advancements in storage ability to reach your dreams.The First Computer weighed 30 short tons (27 t), was roughly 8 feet (2.4 m) by 3 feet (0.9 m) by 100 feet (30 m), took up 1800 square feet (167 m²), and consumed 150 kW of power. Today you carry more computing power with your smartphone in your shirt pocket. Don't under estimate technology.
But to get enough power for your smart phone to be smart, takes the same amount of electrical power as your refrigerator---not the power for the phone itself but the power needed to support the infrastructure behind it then multiply that times the number of smart phones around the country and you get an idea of what it will take to continue in the life style you've been accustomed to.
