TECHNOLOGY

2. WHAT IS GREEN TECHNOLOGY?
▶ ENVIRONMENTAL FRIENDLY
TECHNOLOGY.
▶ CONSERVE NATURAL RESOURCES
AND THE ENVIRONMENT –
SUSTAINABLE DEVELOPMENT.
▶ RADICAL THINKING TO CHANGE.
▶ INNOVATIVE TECHNOLOGY.
▶ RECYCLING.
▶ RENEWING.
▶ REDUCING.
▶ RESPONSIBILITY.
GOALS OF GREENTECHNOLOGY

3. TYPES OF GREEN TECHNOLOGY
▶ GREEN ENERGY.
▶ GREEN BUILDING.
▶ GREEN PURCHASING.
▶ GREEN CHEMISTRY.
▶ GREEN NANOTECHNOLOGY.

4. GREEN ENERGY
▶ Green energy comes from natural sources such as
sunlight, wind, rain, tides, plants, algae and geothermal
heat.
# These energy resources are renewable, meaning
they're naturally replenished.
▶ Reasons for the Need of Green Energy
1: Natural resources used in the energy generation
process is on the decline.
2: Increasing pollution caused by the non renewable
sources.

5. TYPES OF GREEN ENERGY
Solar power -
Solar energy technologies use the energy of the sun to light homes,
heat water and generate electricity.
▶ Solar Energy Is an Abundant Energy Source.
▶ Solar Energy Is Renewable.
▶ Solar Energy Is Safe to Produce.
▶ Low Maintenance and Running Costs
▶ Solar Energy Is Applicable Everywhere.
▶

6. TYPES OF GREEN ENERGY
WIND POWER-
Use the energy of the wind to generate electricity. One of
the oldest and the most efficient energy of all renewable
energies.
▶ Wind Energy Reduces energy imports.
▶ Wind Energy Is Renewable.
▶ Wind Energy Is Safe to Produce.
▶ Low Maintenance and Running Costs.
▶ Contributes to sustainable development

7. TYPES OF GREEN ENERGY
Hydroelectric energy-
▶ Called hydroelectric power or hydropower.
▶ Uses the energy of moving water.
▶Generates electricity by harnessing the gravitational force
of falling water.
Biomass energy-
▶Biomass is organic material that comes from plants and
animals.
▶ It is also a Is Renewable source of energy.
▶ Less expensive than fossil fuels.

8. GREEN BUILDING
Green building is the structures that are
environmentally responsible and resource-efficient
throughout a building's life-cycle from siting to design,
construction, operation, maintenance, renovation and
deconstruction.
Advantages
▶ Less energy consumption than a building of
comparable size.
▶ Saves more potable water demands than a normal
building of same size.
▶ Reduces cost of operation in the long term.
▶ Consumers now more environment conscious.

9. GREEN PURCHASING
Product
▶Product dimension includes providing and using engineering
with market-driven trends for green product attributes such
as energy savings, organic clothing, low volatile organic
compounds, green chemicals etc.
▶Greener selection and use of resources results in savings from
less waste, less chemicals and less processing.
▶Wal-Mart has made tremendous strides in greening their
transportation, energy usage, facility design and adoption of
some greener products such as organic clothing.

10. GREEN CHEMISTRY
▶Use of safe, environment-benign substances,
including solvents, whenever possible.
▶Design of processes to maximize the amount of raw
material that ends up in the product.
▶ Design of energy efficient processes.
▶Best form of waste disposal, not to create it in the
first place.

11. GREEN NANOTECHNOLOGY
▶ It will help provide clean water to billions.
▶ Ability to recycle after use.
▶Nanotechnology can also help in waste
management and environmental remediation.
▶A large number of efficiency issues stopping the
extensive use of renewable energy generation can
be solved by using nanotechnology.

12. THE POSITIVE EFFECTS OF
GREEN TECHNOLOGY
▶ Can bring economic benefits to certain areas.
▶Requires less maintenance so you don’t have to shell
out a lot of money to operate it.
▶ Renewable which means we will never run out.
▶ Does not emit anything harmful into the air.
▶ Reduce the amount of waste and pollution.
▶Can slow the effects of global warming by reducing
CO2 Emissions.

13. GREEN INNOVATION IN BANGLADESH
▶ Use of GREEN ENERGY in Bangladesh.
▶Use of full Green Factory in Readymade
Garments(RMG) sectors.
▶ Use of Green Technology in new industries like ICT
.
▶ Invention of new Green Product.

14. WHAT WE SHOULD DO NOW?
▶ Rethink about the way we live….
▶ Reducing Exhaustion.
▶ Recycle Waste.
▶ Renew Energy.
▶ Buy and use green product.
▶ Build new Green factory or building.
▶ Think about Green invention.
▶ Try to invent or discover green technology.

15. CONCLUSION
▶Global warming and energy crisis cannot be solved
with one or two years. So we should start using green
technology.
▶It really requires our determination and continue
effort in improving the situation.
▶Green technology will definitely be the solution that
gets the potential in helping us to solve those
problems and improve our environment .
