To everybody who thinks energy right now is too expensive.
A couple of friends and I built a bike generator station for five bikes. We are using DC-Motors as dynamos and lead batterys for buffering the output.
Five bikers in total can generate between 220W to 250W for an extended time. Let assume they bike at 200W for five hours. They then will have generated one kilowatthour of electricity, which costs 25ct. I'm pretty sure they will be happy with their five cent per person when they get off the bikes after five hours.
Bike generators are powered by people. People biking require time. What is the labor or opportunity cost of having all of these people sustaining 250W per hour or essentially a .25kW-hour? Just a thought but that doesn't sound cheap.
That's exactly what jsilence is saying. Energy from the grid is so incredibly cheap that you're using it without a second thought on things you would never consider doing without a grid. It could go up hundredfold before becoming expensive.

Energy is dirt cheap.
