Whats the difference between passive and active solar energy?
Passive systems are structures whose design, placement, or materials optimize the use of heat or light directly from the sun. Active systems have devices to convert the sun's energy into a more usable form, such as hot water or electricity.
What is the difference between passive and active solar energy quizlet?
What is the difference between active and passive solar heating? Passive solar heating uses building design to utilize sunlight, while active solar heating uses technology.
Is active or passive solar more efficient?
Active solar energy has benefits, such as not needing a power source other than the sun. Active solar energy also utilizes external devices (solar panels) which are low maintenance and very dependable. Passive solar energy, on the other hand, is typically cheaper than active solar energy.
What is the difference between an active and a passive solar system for heating water?
The main difference between active and passive solar hot water heaters is that active systems use mechanics, such as pumps, to move liquid through the system; passive systems rely on gravity.
What are the advantages of active solar energy?
Heating your home with an active solar energy system can significantly reduce your fuel bills in the winter. A solar heating system will also reduce the amount of air pollution and greenhouse gases that result from your use of fossil fuels for heating or generating the electricity.

What is active solar heating?
Active solar heating systems use solar energy to heat a fluid — either liquid or air — and then transfer the solar heat directly to the interior space or to a storage system for later use. If the solar system cannot provide adequate space heating, an auxiliary or back-up system provides the additional heat.
