Sustainable Development & Energy

Or How we can make Earth a Greener Planet.

Global warming is a Modern problem -

Complicated, involving the entire world, tangled up

with issues of poverty, economic development and

population growth. Dealing with it will not be easy.

Ignoring it will be worse.

Presentation by: Amit KumarTata BP Solar India Ltd.

What is Energy ?

It's simple - Energy is the ability to do work.

Even though you can't ever really see it, energy

causes millions of different actions & reactions

to occur every single day.

In fact, whenever something moves, heats, cools,

grows, changes, produces light or sound;

Energy is involved.

Solar energy reaching Earth: 1000W/sqm.

The amount of Solar energy intercepted by

the Earth every minute is greater than amount

of fossil fuel the world uses every year.Society through the ages

have worshipped Sun as God.

Climate Change - Fact or Fiction:

Scientists say average global temperatures

have varied by less than one degree since the

dawn of human civilization

But world heated up by 0.6C last century

and 90s were the warmest decade on record.

A global rise of between 1.4C and 5.8Cis expected by 2100.

Sea levels rose between 10-20cm worldwide

during the 20th Century. A further rise of

between 9cm and 88cm is predicted by 2100.

Way Forward:

I urge you to look ahead, beyond the Protocol, which takes us only to year2012. The longer-term challenge is to promote the use of low-carbon energysources, low greenhouse gas technologies and renewable energy sources

Kofi Annan, UN Secretary-General,Kyoto Protocol Meet, Dec 2004.

Renewable Energy sources such as PV,

Wind, Biomass, Tidal Energy deal with

generation of Green electricity.

Alternative Energy encompasses all of

above and emerging clean systems such

as fuel cells, low carbon technologies, etc

Sun is the single largest source of

clean and green energy.

Sun: Energy Unlimited

Biomass: Vegetation uses photosynthesis to

convert solar energy to chemical energy.

Hydroelectric dams and wind turbines are

powered by solar energys interaction with

atmosphere & resultant weather phenomena

Fossil fuels are ultimately derived from

solar energy captured by vegetation in the

geological past.

In direct form, solar energy is available as:

Heat

Light

Solar Technology: Classification

Solar design in architecture

Solar heating systems

Solar cooking

Solar lighting

Solar Photo Voltaic

Solar thermal electric power plants

Solar pond

Solar chemical

The concept of Vaastu-Shastra is based

on the principle of Passive Solar Design,

i.e local climate, materials & masonsA well ventilated and naturally lithome reduces electric load by 20%

Solar Cooking :

A solar box cooker traps the sun's energy in an

insulated box.

Such boxes have been successfully used for

cooking, pasteurization and fruit canning.

Solar cooking is helpful in many developing

countries, both reducing demand for local

firewood and maintaining a cleaner breathing

environment for the cooks.

Parabolic type cookers focus the suns rays at

the base of the cooking vessel to simulate

conventional cooking devices.

Solar Lighting (Natural) :

Solar lighting or daylighting is the use of

natural light to provide illumination.

Daylighting offsets energy use in electric

lighting systems and reduces the cooling load on

HVAC systems.

Window orientation, exterior shading, sawtooth

roofs, clerestory windows, light shelves, skylights

and light tubes are among the many daylighting

features.

Daylight saving time (DST) is a method of

utilising solar energy by matching available

sunlight to hours of day when most useful.

Solar Thermal for Power :

Solar thermal energy can be used to heat a heat

exchanger to high temperature and the heat is

used to produce electric power or for other

industrial purposes.

Power towers (or central tower) use an array of

flat, moveable mirrors (called heliostats) to focus

the sun's rays upon a collector tower (the target).

The energy at this point of concentrated

sunlight is transferred to a substance that can

store the heat for later usage.

Power Tower:

Solar Concentrators :

Solar energy converted to heat in concentrator typecollector can be used to boil water into steam todrive a steam engine or steam turbine.

The concentrating collector can be a troughcollector, parabolic collector, or power tower.

Concentrating collector with Sterling engine:

The Sterling engine is a type of heat engine whichuses a sealed working gas (i.e. a closed cycle) anddoes not require a water supply.

A solar Sterling system holds the record forconverting solar energy into electricity (30%at 1,000 watts per square meter).

Solar Chemicals & Bio-fuels :

The oil in plant seeds, in chemical terms, very

closely resembles that of petroleum.

Since invention of the Diesel engine, many

have been using this form of captured solar

energy as a fuel for use in any diesel engine or

generator and known as Biodiesel.

Solar chemical refers to a process that harnesses

solar energy by absorbing sunlight in a chemical

reaction like photo-synthesis without using

living organisms.

A possible application is splitting water to

produce hydrogen and oxygen.

Solar Ponds :

Solar pond is a pool of water which collects and

stores solar energy.

Layers of salt solutions with increasing

concentration (& density) to a certain depth,

below which the solution has a uniform high salt

concentration.

When solar radiation is absorbed, density

gradient prevents heat in lower layers from

moving upwards by convection.

This means that the temperature at the bottom

of the pond will rise to over 90C while

temperature at the top is at 30C.

Solar Pond developed by

TERI at Bhuj, Gujarat is

one of the largest in world!

Solar Photo Voltaic :

Solar cells, also referred to as photovoltaic cells,

are devices or banks of devices that generate

electricity directly from sunlight.

A set of cells make a module, and due to its

modular design, they can be designed from a

small calculator to large MW size plants.

Solar PV power plants can be either stand-alone

(with batteries) or grid connect.

PV power is a clean and green technology

which produces no noise and pollution.

PV is perfect answer where conventional grid

supply is unavailable or unviable.

(This does not include cost oftransportation, maintenance,

spares & replacements for DG)

Points to note:

Solar PV is a clean & green energy.

The systems have low maintenance

as they have no moving parts.

When compared to DG sets, Solar

can be a cost effective alternative.

Solar is an ideal solution for lighting

and modular nature ensures that they

can be designed for any capacity.

Incentives :

The Government offers 80% depreciation on all solar products on

year 1 of its installation. Corporate tax rate is at 33.6%

Some states have initiated the feed-in

tariff system but is more suited for wind.

Integrated Energy Policy does recognizethe importance of solar in the energy mix

but no incentive structure in place.
