Title: What is Renewable Energy ?


1
What is Renewable Energy ?Renewable
Energy is the energy that is derived from Natural
processes that are replenished constantly. In its
various forms, it derives directly or indirectly
from the sun, or from heat generated deep within
the earth.- International Energy Agency
(IEA)Renewables Information 2003

Slogan given by Ministry of New Renewable
Energy, Govt of India for a cleaner and greener
tomorrow

3
Common forms of Renewable Energy
  • Solar
  • Wind
  • Tidal
  • Wave
  • Geothermal
  • Biomass
  • Hydropower

4
SOLAR ENERGY
CAPTURING RADIANT ENERGY OF THE SUN TO PRODUCE
HEAT OR ELECTRICAL ENERGY
5
Solar Energy Potential in India
  • Solar water heaters and cookers have proved the
    most popular so far and solar photo-voltaics for
    decentralized power supply are fast becoming
    popular in rural and remote areas.
  • More than 700000 PV systems generating 44 MW have
    been installed all over India.
  • Under the water pumping program more than 3000
    systems have been installed so far and the market
    for solar lighting and solar pumping is far from
    saturated.
  • Solar drying is one area which offers very good
    prospects in food, agricultural and chemical
    products drying applications.

6
WIND ENERGY
Converting the force of wind into mechanical or
electrical energy
7
Wind Energy Potential in India
  • India now ranks as a "wind superpower" with an
    installed wind power capacity of 1167 MW and
    about 5 billion units of electricity have been
    fed to the national grid so far.
  • In progress are
  • Wind resource assessment program
  • Wind monitoring
  • Wind mapping,
  • covering 800 stations in 24 states with 193
    wind monitoring stations in operations.
  • Altogether 13 states of India have a net
    potential of about 45000 MW.

8
TIDAL ENERGY
  • Converting the movement of water into mechanical
    or electrical energy
  • Tidal energy is clean, sustainable and renewable,
    and a reliable and consistent energy source.
  • Tidal energy utilizes the rise and fall in sea
    levels due to currents and has the potential to
    convert hydel energy into electricity with an
    efficiency of 80.

9
Tidal Energy Potential in India
  • Indias geographical location, with oceans and
    seas on three sides, has brought into focus its
    enormous potential to harness tidal energy a
    fact that has been recognized by the Government
    of India.
  • An estimated combined potential of 15,000 MW at
    the Gulf of Kutch and the Gulf of Cambay on the
    west coast and Durgaduani creek in the state of
    West Bengal on the east coast has been
    identified.
  • The Kutch tidal power project is expected to
    generate electricity at a cost as low as US
    0.023 per unit. This project is being appraised
    for its technical feasibility and economic
    viability.

10
WAVE ENERGY
  • The interaction between wind and the surface of
    sea results in waves.
  • Waves drive water in an air chamber to rise and
    fall, and the resulting airflow can turn a
    turbine to generate electricity.


11
Wave Energy potential in India
  • The Annual Wave Energy potential for Indian
    coasts is 175-200 MWH/m and wave power potential
    varies from 5KW/m to 47KW/m depending on
    locations and monsoon conditions.

12
Geothermal Energy
  • Extracting natural heat from within the earth for
    direct heating and/or to produce electricity.
  • Private companies and state governments have been
    attempting to exploit this vast reserve of FREE
    energy
  • Government of Gujarat has framed a new policy and
    passed a government resolution (No
    REP-102000-502-B) aimed at formulating an
    incentive policy for solar photo voltaic,
    geothermal, waste utilization, biomass, etc

13
BIOMASS ENERGY
  • Burning organic matter such as wood or
    agricultural materials to produce heat energy.
  • Methane gas can be provided
  • from organic wastes.
  • 4 TYPES Biogas, Bioethanol, Biodiesel, Second
    generation Biofuels

14
Biomass Energy Potential in India
  • Most common source of biomass is wood waste and
    agricultural wastes. In India development of
    biomass gasification has received  serious
    attention with establishment of biomass research
    centers and gasifier action research centers,
    which have played a key role in up gradation and
    adoption of suitable technologies, testing,
    monitoring and development of biomass
    gasification systems.  
  • In India more than 2000 gasifiers are estimated
    to have been established with a capacity in
    excess of 22 MW and a number of villages have
    been electrified  with biomass gasifier based
    generators. MNES has actively promoted research
    and development programs for efficient
    utilization of biomass and agro wastes and
    further efforts are on.
  • Biomass gasification offers immense scope and
    potential for
  •  Water pumping
  • Electricity generation 3 to 1 MW power plants
  • Heat generation for cooking gas smokeless
    environment
  • Rural electrification means  better healthcare,
    better education and improved quality of
    life.
  • Two major forms of biofuels are bio-diesel and
    bio-ethanol, keeping this need in mind Bharat
    Petroleum has signed a deal with British D1 oils
    to become largest producer of Jatropha oil by
    2011

15
HYDROPOWER
  • Generating electricity from falling water.
  • Radiant energy ?Kinetic energy of water
    ?Potential energy ?Mechanical energy ?Electrical
    energy

16
Role of Hydel Power in India
  • Today there is a strong push for large hydro
    projects in India. While the pro-hydro lobby is
    working towards meeting Indias full potential,
    the anti-hydro-power groups are targeting those
    projects which they believe are violating
    environmental and human rights norms. Despite
    growing number of oppositions to hydro-power, the
    Indian government is very optimistic to achieve
    its potential.
  • The Indian government considers hydropower as a
    renewable economic, non-polluting and
    environmentally benign source of energy. The
    exploitable hydro-electric potential in terms of
    installed capacity is estimated to be about
    148,700 MW (See Table 1) out of which a capacity
    of 30,164 MW (20.3) has been developed so far
    and 13,616 MW (9.2 ) of capacity is under
    construction

17
URBAN WASTE
  • The population growth has put tremendous pressure
    on the quality of Environment of urban life.
  • The residents generate various kinds of wastes
    of biodegradable and non biodegradable
    categories.
  • The impact created by these wastes on the
    environment is enormous, if proper disposal and
    management options are not applied.

18
Energy Generation from Urban Wastes
Energy recovery from urban wastes using
biomethanation, pyrolysis, gasification
and incineration and obtaining biogas from sewage
treatment.
  • Sewage treatment plant at Surat
    Biomethanation plant at Vijaywada

19
Role of Renewable Energy Resources in India
  • Short term strategy
  • Administered pricing mechanism
  • Institutional reforms to be consolidated for
    deregulation
  • Optimum utilization of existing assets
  • Production systems to be made efficient,
    transmission and distribution losses to be
    reduced
  • RD transfer of technologies to be promoted
  • Energy efficiency improvement in accordance with
    national and socio-economic and environmental
    priorities
  • Energy efficiency and emission standards to be
    promoted
  • Labeling programs for products
  • Adoption of energy efficient technologies in
    giant industries

20
Role of Renewable Energy Resources in India
  • Long term strategy
  • Demand management through greater conservation of
    energy, optimum fuel mix, increasing reliance on
    rail for movement of goods and passengers and
    shift to emphasis on utilizing mass movement and
    transport systems for public rather than private
    transports
  • Better urban planning to reduce need for energy
    in transport sector
  • Shift and emphasis to solar, wind, biomass energy
    sources
  • Emphasis on research and development, transfer
    and use of energy efficient technologies and
    practices in the supply and end-use sectors.

Summing up the ADVANTAGES of RENEWABLE ENERGY
  1. It is environmentally friendly.   It's clean and
    mostly emission-free.
  2. It is inexhaustible.   Unlike fossil fuels,
    renewable energy can be replenished quickly. It
    will not run out ordeplete resources.
  3. It does not require fuel.   It comes from
    natural resources which can be used directly to
    generate energy orelectricity.
