WAYS OF TAPING SOLAR ENERGY
1) SOLAR THERMAL. Solar thermal technology uses the sun's energy, to generate low-cost, environmentally friendly thermal energy. This energy is used to heat water or other fluids, and can also power solarcooling systems.
2)SOLAR PHOTO VOLTAIC.

First molten salt storageuse of molten salt (Sodium nitrite and nitrate) to capture and
store the sun's heat. The very hot salt was stored and used when needed to produce steam to drive a turbine/generator that
produces electricity long into the night.

SOLAR PHOTOVOLTAIC
Solar cells, also called photovoltaic (PV) cells
convert sunlight directly into electricity.
PV gets its name from the process of converting light (photons) to electricity (voltage),

Projects(studying the potential for wind power in your area)
Using anemometer
8 kph (2 m/s) minimum is required to start rotating most small wind turbines.
12.6 kph (3.5 m/s) is the typical cut-in speed, when a small turbine starts generating power
36–54 kph (10–15 m/s) produces maximum generation power.

Energy sufficiency ,Energy efficiency and renewable energy - the pillars of
sustainable energy.
For development process to be sustainable increase the efficiency of energy utilities and processes, conserve energy and explore renewable sources of energy.
Decentralization of energy Production, Processing, Transmission, Consumption and Disposal

Project ideas
For cooking:
Use of fossil fuel (LPG)– not sustainable.
Think of using locally available sources.
Biomass fuel briquettes.
gasification.

• Cooks all bulk meals fast
• Saves fuel cost by over 25% as compared to LPG
• Enhances food and flavour
First Energy Pvt. Ltd., is an alternative energy company based in Pune, India that applies biomass and gasification technology to heating applications, specifically home and commercial cooking. It was launched in 2005 as BP energy, a 100% subsidiary of British Petroleum

NEW Energy conservation ideas
Decreasing the load of AC’s
AC’s no more a luxury, will become a basic need with increasing global average temperature.
Ideal thermal comfort at a room temp. of 27 deg C.
In summer room temp. can go up to 35deg C during night.
Can reduce the load or avoid using AC’s -HOW?

Develop cost effective materials
Materials already in the market costly Rs.10-15 per sq.ft.
Try using shade net.

DC lighting
HOUSES use AC power supply.All most all devices uses AC power.UPS –AC power to Battery (DC power)
DC converted back to AC power –lot of wastage in this process (40-45%)LED lights uses DC power,also consumes less energy.CAN DEVELOP A MODELSolar panel Battery DCLED lighting.(lots of saving in cost)

Using solar PV without Battery
-Considerably reduces the initial cost .
-Reduces the recurring cost.
- For lighting(LED) during day time.
- Running a DC fan during day time.
- Try for some more devices.
