Well, you can't go 100% in your area but there are things you can do . You have a window somewhere so you can place a high watt solar panel outside your home with tracker to move with the sun to draw in more power. You can install high efficiency lights, you can get an LCD TV.
But yeah, you're pretty much stuck for the most part as long as you're in that area. But for the millions of others who have a backyard and a patio or roof, they can easily do it.
I realize that science probably isn't your strongest suit, but here it goes.
Solar panels are about 20% efficient, and produce about 12 to 14 watts per hour per square foot. Let's assume a really fancy solar panel that can generate 20W/sqft on a window that is 3 feet by 3 feet. The panel would still only generate (20 W/hr/sqft) * (9 sqft) = 180 W/hr. That's not enough to run a microwave even if the sun is shining really really brightly.
But let's not worry about details. Maybe you want to run a small radio. And let's be generous, and say that this window faces the sun 8 hours a day -- every day, regardless of season -- and that the panel can pump out a constant 180 W/hr for those 8 hours. This
magical system will still only produce less that 530 kWh per year.
Remember, that the average American home uses ~11000 kWh per year, at an average cost of $0.12/kWh. With those prices, the generated electricity from our magical system is worth about $65 per year.
