(1) According to the working principles of wind turbines and solar panels, it is known that installing solar panels on windmill blades of wind turbines can convert wind energy and solar energy into electric energy at the same time. If they are connected to a storage battery, the storage battery stores electrical energy in the form of chemical energy. In the process of storing electric energy, it is to convert electric energy into chemical energy.

So, the answer is: wind; Chemistry.

(2) It is known that the rated voltage of the energy-saving lamp L 1 is 12V and the rated power is 8W; And then from the power formula:

Resistance L 1 of energy-saving lamps? R=U amount 12P amount1= (12v) 28w =18ω;

It is known that the rated voltage of energy-saving lamp L2 is 12V and the rated power is 5W. And then from the power formula:

What did Lantern L2 do in one minute? W2=P forehead 2t = 5w×60s = 300j；;

Answer: The resistance of energy-saving lamp L 1 is18 Ω; Lantern L2 consumes 300J. Electricity per minute.

(3) According to the analysis, corridor lamp L 1 and outdoor colored lamp L2 are connected to the parallel circuit, and light control switch S 1 is connected to the main road; Voice switch S2 is connected in series on the branch of corridor lamp L 1, as shown in the figure:
