PASSIVE SOLAR ENERGY

Uses and FunctionsUses and FunctionsUSES & FUNCTIONS

• HEATING

• ELECTRICITY

• COOLING

• HOT WATER

Producing EnergyProducing Energy-Heating:-Heating:

Sun space- its built on a side wall of a Sun space- its built on a side wall of a building, sunlight passes through and building, sunlight passes through and warms it. It’s made of material that warms it. It’s made of material that absorbs heat, and proper ventilation absorbs heat, and proper ventilation allows heat to circulate into the building allows heat to circulate into the building during the day and warms it at nightduring the day and warms it at night-Electricity:

• Photovoltaic- the panel consist of solar cells that transform the energy from the sun to electricity. 1 Panel= A 12V Battery

WHERE IS IT USED? Passive Solar Energy is being used all

over the United States, as people become more aware of this technology and design.

Pro’s- better for environment, cheaper, a renewable and sustainable energy source.

Con’s- In some cases the materials necessary for passive solar energy may be somewhat expensive.

Challenges of Making it Mainstream

The government would need to make standards for more efficient houses using passive solar materials and designs.

Need to make passive solar materials cheaper and needs to be advertised more to make people realize they have options.

Need to make inefficient products harder to get and tax the people who have inefficient houses.

Will it be mainstream?Will it be mainstream?

► It is quiet possible to make passive solar It is quiet possible to make passive solar energy mainstream, as long as the Gov. energy mainstream, as long as the Gov. and Companies take the right steps, and Companies take the right steps, such as;such as;

► More well knownMore well known► Easier to come byEasier to come by► CheaperCheaper
