Do cells extract energy
Proteins extract the energy from food via Enzymes.
No, since there is little or no free hydrogen on Earth. (plenty in the sun, and it is a natural resource there.) There is bound hydrogen on Earth (mostly water), but the energy required to extract it is greater than the energy it gives up in burning.

One can purchase a good effective energy drink at almost every supermarket. A large selection of energy drinks - such as red bull - is most certainly available at a local supermarket.

You burn them in some type of engine to extract their energy.

An electric turbine in a large machine that has the ability to extract raw energy through wind, water, or other such natural source and convert it into a workable form of energy. One example of electric turbines at work can be seen with windmills.

Not all organisms can create their own energy from the sun, only if you mean plants. We, humans, can't create energy from sun directly, but can indirectly create energy from plants through the food chain. Plants create energy through the process of photosynthesis, and we humans either eat the plant or eat the organism that ate the plant to obtain energy. Hope that helps!
