GREEN TECHNOLOGY
ABSTRACT
The goal of the "Green Building" project is to reduce the
impact of construction on the environment. By doing this Intel joins the
world's efforts in sustainable construction. The Green Building project differs
from conventional building projects by assigning equal priorities to
economical, social, and environmental goals. The new Intel R&D building,
located in Haifa, Israel, is designed per the Leadership in Energy &
Environmental Design (LEED*) rating system. These were the objectives of the
design process:
·
To
achieve energy and water savings.
·
To
incorporate environmental friendly materials into the building.
·
To
implement waste and recycling policies.
·
To
provide a high-quality internal environment.
·
To
position and plan the site to reduce the impact on the environment.
The new Intel R&D building is now under construction and is
undergoing a certification process. Once awarded, it will become Intel's first
certified Green Building worldwide!
This project was initiated to address
the need for a "smart" building. The Green Building concept was found
to be the most suitable for this purpose, particularly for an R&D building.
Research shows that such a building improves tenants' satisfaction and health,
enabling higher employee productivity; and it reduces energy and maintenance
costs for the owners. The estimated ROI due to operational costs is
approximately five years.
In this paper we show the innovation, logic, drivers, and triggers that
helped us overcome significant challenges in dealing with an inexperienced
local building industry, and in driving innovation in a large organization. Our
engagement with the local construction industry adds a new dimension to the
concept of Intel social responsibility. Our key message is that it is possible
to execute a local and innovative initiative successfully, even in global
corporations, once the initiative supports the corporate values.
The Global climate change argument pales in comparison to the
consequences the world faces, if realistic solutions are not found to address
the world energy crisis. Green Technology encompasses a continuously evolving
group of methods, materials and techniques for generating energy and non-toxic
products. The present expectation is that this field will bring innovations and
changes in daily life, of similar magnitude, to the information technology
predominance over the last two decades. Protection of the environment is needed
from various human activities. Waste, pollution, loss of biodiversity,
introduction of invasive species, release of genetically modified organisms and
toxics are some of the issues relating to environmental protection.
Environmental technology is the application of environmental science and green
chemistry to conserve the natural environment and resources, and to curb the
negative impacts of human involvement. Sustainable development is the core of
environmental technologies.
INTRODUCTION
Environmental technology (abbreviated as
envirotech) or green technology
(abbreviated as greentech) or
clean technology (abbreviated as cleantech)
is the application of one or more of environmental
science,
green chemistry, environmental monitoring and electronic devices to monitor,
model and conserve the natural environment and resources,
and to curb the negative impacts of human involvement. The term is also used to
describe sustainable energy generation technologies such as Photovoltaics, Wind Turbine's, Bioreactors, etc. Sustainable
development
is the core of environmental
technologies. The term environmental
technologies is also used to describe a class of electronic devices that
can promote sustainable management of resources.
Basically, green technology is that in
which the technology is environmentally friendly and is created and used in a
way that conserves natural resources and the environment. Green technology is a
field of new, innovative ways to make changes in daily life. Currently, this
Clean Technology is in the beginning stages of its development, so the future
will only bring bigger and better things for this field.
DEFINITION
Green technology is the future of this society. It's main goal is to
find ways to produce technology in ways that do not damage or deplete the
Earth's natural resources.
In addition to not depleting natural
resources, green technology is meant as an alternative source of technology
that reduces fossile fuels and demonstrates less damage to human, animal, and
plant health, as well as damage to the world, in general.
Next, green technology is so that products can be re- used and recycled.
The use of green technology (clean
technology) is supposed to reduce the amount of waste and pollution that is
created during production and consumption.
TYPES
OF GREEN TECHNOLOGY
·
Energy: The most
important and urgent concern and want for green technology is for energy
purposes. We need better, more efficient was to produce energy without burning
all the world's coal and using all the world's fossil fuels and natural
resources.
·
Building:
Basically,
speaking, green building is an innovative way to build buildings and houses so
to use the tools and materials most efficiently towards the environment.
·
Preferred
purchasing: Green
preferred purchasing is a new way to find products and methods of production
that have the smallest impact on the environment. This searching and
researching yields products that are deemed to be the environmentally preferred
purchases.
·
Chemistry:
Green
chemistry is the application of chemical products that eliminate harm to the
environment.
RENEWABLE
ENERGY
Renewable energy is energy that can be replenished easily. For
years we have been using sources like wood, sun, water, etc. for means for
producing energy. Energy that can be produced by natural objects like wood,
sun, wind, etc. is considered to be renewable.
Renewable energy is energy which comes from natural resources such as sunlight, wind, rain, tides, and geothermal heat, which are renewable (naturally
replenished). About 16% of global final energy consumption comes from
renewables, with 10% coming from traditional biomass, which is
mainly used for heating, and 3.4% from hydroelectricity. New renewables
(small hydro, modern biomass, wind, solar, geothermal, and biofuels) accounted
for another 3% and are growing very rapidly. The share of renewables in electricity
generation
is around 19%, with 16% of global electricity coming from hydroelectricity and
3% from new renewables.
Wind power is growing at
the rate of 30% annually, with a worldwide installed capacity of 238,000 megawatts (MW) at the end
of 2011, and is widely used in Europe, Asia, and the United States. At the end of 2011 the photovoltaic (PV) capacity
worldwide was 67,000 MW, and PV power stations are popular in Germany and Italy. Solar thermal power stations
operate in the USA and Spain, and the largest of these is the 354 MW SEGS power plant in the Mojave Desert. The world's largest geothermal power installation is
the Geysers in California, with a rated
capacity of 750 MW. Brazil has one of the
largest renewable energy programs in the world, involving production of ethanol fuel from sugarcane, and ethanol
now provides 18% of the country's automotive fuel. Ethanol fuel is also widely available
in the USA
WATER PURIFICATION
Water purification: The whole
idea/concept of having dirt/germ/pollution free water flowing throughout the
environment. Many other phenomena lead from this concept of purification of
water. Water pollution is the main enemy of this concept, and various campaigns
and activists have been organized around the world to help purify water.
Considering the amount of water usage that is under current consumptions, this
Concept is of utter Importance.
Water purification is the process of removing undesirable chemicals,
biological contaminants, suspended solids and gases from contaminated water.
The goal is to produce water fit for a specific purpose. Most water is purified
for human consumption (drinking water) but water purification may also be
designed for a variety of other purposes, including meeting the requirements of
medical, pharmacology, chemical and industrial applications. In general the
methods used include physical processes such as filtration, sedimentation, and
distillation, biological processes such as slow sand filters or activated
sludge, chemical processes such as flocculation and chlorination and the use of
electromagnetic radiation such as ultraviolet light.
The purification process of water may reduce the concentration of
particulate matter including suspended particles, parasites, bacteria, algae,
viruses, fungi; and a range of dissolved and particulate material derived from
the surfaces that water may have made contact with after falling as rain..
It is not possible to tell whether water is of an appropriate quality by
visual examination. Simple procedures such as boiling or the use of a household
activated carbon filter are not sufficient for treating all the possible
contaminants that may be present in water from an unknown source. Even natural
spring water – considered safe for all practical purposes in the 19th century –
must now be tested before determining what kind of treatment, if any, is
needed. Chemical analysis, while expensive, is the only way to obtain the
information necessary for deciding on the appropriate method of purification
SEWAGE
TREATMENT
Sewage treatment is conceptually
similar to water purification. Sewage treatments are very important as they
purify water per levels of its pollution. The more polluted water is not used
for anything, and the least polluted water is supplied to places where water is
used affluently. It may lead to various other concepts of environmental
protection, sustainability etc.
Sewage treatment, or domestic wastewater treatment, is the process of
removing contaminants from wastewater and household sewage, both runoff (effluents) and domestic.
It includes physical, chemical, and biological processes to remove physical,
chemical and biological contaminants. Its objective is to produce an
environmentally-safe fluid waste stream (or treated effluent) and a solid
waste (or treated sludge) suitable for
disposal or reuse (usually as farm fertilizer). Using
advanced technology it is now possible to re-use sewage effluent for drinking
water, although Singapore is the only
country to implement such technology on a production scale in its production of
NE Water.
SOLID
WASTE MANAGEMENT
Solid waste
management
is the purification, consumption, reuse, disposal and treatment of solid waste that undertaken
by the milk government or the ruling bodies of a city/town. Waste management is
the collection, transport, processing or disposal,
managing and monitoring of waste materials. The
term usually relates to materials produced by human activity, and the process
is generally undertaken to reduce their effect on health, the environment
or aesthetics. Waste
management is a distinct practice from resource recovery which focuses
on delaying the rate of consumption of natural resources..
Waste management practices differ for developed and developing nations, for urban and rural areas, and for residential and industrial producers.
Management for non-hazardous waste residential and
institutional waste in metropolitan areas is usually the responsibility of local government authorities,
while management for non-hazardous commercial and industrial waste is usually the
responsibility of the generator.
ENERGY
CONSERVATION
Energy conservation is the
utilization of devices that require smaller amounts of energy in order to
reduce the consumption of electricity. Reducing the use of electricity causes
less fossil fuels to be burned to provide that electricity.
Energy conservation refers to efforts made to reduce energy consumption.
Energy conservation can be achieved through increased efficient energy use, in conjunction
with decreased energy consumption and/or reduced consumption from
conventional energy sources. An energy conservation act was passed in 2001.
Energy conservation can result in increased financial capital, environmental quality, national security, personal security, and human comfort. Individuals
and organizations that are direct consumers of energy
choose to conserve energy to reduce energy costs and promote economic security. Industrial and
commercial users can increase energy use efficiency to maximize profit.
CONCLUSION
Information technology has become necessity to human development but we
shouldn’t forget the needs of human existence provided by our natural
environment. For real successful development of mankind we need to integrate
manmade technologies with nature in a way that neither harms the other.
According to a study, although 83% companies realize the global warming
problem, still, 80% are not willing to make significant changes for the
environment. But positive actions by technology giants like Intel and Microsoft
in preservation of energy by developing new, more efficient technologies and
the spread of awareness for environmental issues would help. IT manufacturers
are designing products that are not only good for the environment but also more
affordable, if not cheaper than current technology. From contribution of IT
industry and awareness spread by environmentalist, including celebrities and
political leaders, hopefully green technology will be the only technology used
in the near future.
