Science- alternative use of kinetic energy

This will really happen sooner or later .When there are no more fossil fuels , I guess that everything, all of them, their prices would rise tremendously. Every family,by then, would have some solar panels or some sort of thing like that , it will be very common, everything is so high-tech.so , people will be using solar panels . nowadays , some people have small windmills outside their houses (for terracces and bungalows )that will spin when there is wind ,which is for decorative uses ,will be be used to create elactricity . but wind is unpredictable , so I thought of something , in taps , where the water flows out when the it is on, ther will be a mini turbine in the tap , though it will not spin very fast , but people use taps every single day , many times a day .so the turbine will spin when you use water , even in those showers . everyone showers , so lots of kinetic energy can be converted into electrical energy .i think many things will have turbines in them to convert in to electricity . alternative use of kinetic energy :if people use electricity to work exercising equipment, example, a trackmill so when the person runs on the track (holding handle ) the dynamo will convert kinetic energy to electrical energy . and if no one is using the gym equipment, the lights ,which depend on the kinetic energy converted , will not lit up , just like some of the places that use the same method to lit up the place .
