Candles (of whatever color) are not used to produce electricity, they are used for light, and for ceremonial purposes.
Mother Nature, lightning must be the first to produce light from electricity.
it can use 500volts of electricity
-- Candles must be manufactured. You can't just dig them out of the ground in a usable form. -- Coal contains more chemical energy than candles do. You get more energy from burning a pound of coal then you get from burning a pound of candles. -- On the other hand, a power plant that burned candles would operate cleaner than one that burns coal. It might produce just as much carbon dioxide, but I suspect that there might be less sulfur and mercury to worry about.
Fossil fuels produce electricity when they are burned to make steam or smoke which turns generators to make electricity. But we must be careful that we are not burning too much fossil fuels so that we will run out one day. :)

Solar panels must be constantly exposed to light to produce electricity

The answer depends on where the vehicle is registered. In the US and Canada, some states and provinces specifically require headlamps to produce white light. Others say headlamps must conform to the applicable Federal standards (which specify white light). But some states and provinces only say that all front-facing lamps must produce white or yellow (or "white to yellow", or "white or amber", or "white to amber") light. And some state that front lamps must produce white light unless they were originally manufactured to produce another color. Some countries (Brazil, New Zealand, Japan, the Netherlands and others) have in the past permitted headlamps to produce white or yellow light. Some of them still do. France required yellow headlights from the 1930s to the early 1990s; they're no longer required there but they remain permitted. So you will have to check exactly what the vehicle equipment requirements are in your own jurisdiction to have a usable answer to this question.
We must stay in doors. We must take precaution by buying candles, tinned food etc..
Technically YES. But the source of power in Electric cars being DC through batteries, the motor must be DC and not AC.
Water can be used to produce electricity through hydroelectric power plants, which harness the energy of flowing water to generate electricity. This renewable energy source is clean and sustainable, reducing greenhouse gas emissions compared to fossil fuel-based power generation. However, the environmental impact of hydroelectric dams on ecosystems and wildlife must also be considered.
They must be lit for at least 1/2 of a hour.
