Abstract: The invention discloses a power generation and supply system and a method The power generation and supply system comprises a power generating set which makes use of natural energy to generate electric power, and the direct current power generated by the power generating set can be used at the site The power generation and supply system further comprises a water electrolyzing device and a carbinol preparation device The water electrolyzing device makes use of the electric energy generated by the power generating set to electrolyze water into hydrogen and oxygen The carbinol preparation device makes use of the carbon dioxide in the air and the hydrogen prepared by the water electrolyzing device to produce carbinol under the catalysis of catalyst According to the power generation and supply system and the method, the direct current power generated by the power generating set by making use of the natural energy is directly used without being converted to alternating current power or being transported, so the effective conversion ratio of the electric energy can be improved Meanwhile, the power generation and supply system specifically can store the generated electric energy, that is, the electric energy is used to prepare carbinol through carbon dioxide and hydrogen; the carbinol can be stored as an energy source and energy can be obtained from the carbinol combustion; and the carbinol and water can also be used to prepare hydrogen for generation
