1. Role of an individual in conservation of
energy sources
2. INTRODUCTION:-
Energy conservation helps ensure available resources for future generations and also
helps prevent pollution. Most of our current energy sources today are not renewable,
which means that they will eventually deplete. As a member of the Home Owner’s
Association I believe that it is extremely important for us to educate our community
about the importance of energy conservation. Teaching the community that energy is
not a right but a privilege will educate, empower, and make us aware of the
importance of reserving our resources. I strongly believe that education will
encourage us all to do our part in conserving energy. Most people are unaware of the
amount of energy used and the negative effect it has on the environment. As board
members it is our responsibility to share this information for the better of our
community.
4. RENEWABLE ENERGY
The name here speaks for itself, as this energy is derived from resources that are
not finite, and can either be grown, or replaced easily, or are a naturally
occurring phenomenon like the wind and sun. When it comes to renewable and
non renewable energy sources, renewable is the best option in our opinion. It is
sustainable, and eco-friendly for the most part, and will not pollute our planet.
With oil becoming more scarce, it will only lead to rising prices, and demand
continues to remain high, and with developing nations booming, is even still
growing, which sooner or later will become a major issue. This is why we support
the sustainable energy when it comes to renewable and non renewable energy
sources.
5. 1.GEOTHERMAL ENERGY
Geothermal energy is power extracted from heat stored under the earth’s crust. This
power source is generally cost effective, usually reliable, mostly sustainable, and
generally environmentally friendly. Historically, geothermal energy extraction has been
limited to areas near tectonic plate boundaries. Recent advances in technology have
significantly widened the range of viable resources, especially for applications such as
home heating.
6. 2.WIND ENERGY
Wind power is growing at a rate of 30% a year and is harmless to the environment. There
are three minor problems with wind energy however, wind is not available in sufficient
quantities in all locations all of the time, the current turbine technology tends to be
loud, and birds can sometimes fly into the propellers and get killed. Advancements in
technologies are helping to solve or minimize these issues.
7. 3.SOLAR ENERGY
Solar energy has been used by humans since the beginning of mankind I would imagine.
There are three types of solar energy: passive solar energy, active solar energy, and solar
energy created by converting solar radiation into electricity using photovoltaic cells.
Solar energy using photovoltaic or solar cells is currently the fastest growing power
generating technology in the world. Technology in this area is also advancing rapidly with
exciting changes resulting in much greater efficiency and flexibility.
• Solar technology is now poised to play a larger role in the future,
thanks to new developments that could result in lower costs and
improved efficiency
8. 4.HYDROELECTRIC DAMS
Hydroelectric dams use hydro-power to produce electricity. Hydro-power is created from
the force of moving water turning large turbines to create electricity. Modern age large
scale hydroelectric dams however impact the environment through loss of natural habitat,
changes to the downstream riverbed, the disruption of fish spawning, and even the loss of
fish and other species, not to mention forcing people to abandon their farms and homes,
and even abandoning entire cities and villages in certain instances, such as the Three
Gorges Dam in China, which forced the relocation of roughly 1.3 million people.
9. 5.BIOMASS ENERGY
Biomass is biological material from recently living or currently living organisms such as
trees and landfill gasses and alcohol fuels creating from crops such as corn. Burning grease
or ethanol derived from corn to run a vehicle are two common examples of biomass
energy production.
10. NON RENEWABLE ENERGY
Nonrenewable energy sources are natural energy sources that are finite, or in limited supply.
While these sources of energy may at first seem abundant, the supplies will dwindle as we
consume them, eventually exhausting them altogether. This is what we call unsustainable,
as we cannot sustain our reliance on them indefinitely because sooner or later they will run
out. In addition to these resources being finite, not only is the burning harmful to the planet
but also the extraction of these sources of energy have dire consequences on the
environment.
11. 1.CRUDE OIL
Crude oil is a naturally occurring highly toxic combustible liquid primarily made up of
hydrocarbons. Oil is the result of the partial decaying of living organisms occurring in the
rock strata of certain geological formations.
12. 2.COAL
Coal is a combustible black or brownish-black sedimentary rock formed from fossilized
plants. Coal consists of amorphous carbon with various organic and some inorganic
compounds and is normally occurring in rock strata in layers or veins called coal beds.
Coal is another highly toxic element that is bad for the environment, and currently is the
largest source of energy for power plants, referred to as coal fired power plants.
13. 3.NATURAL GAS
Natural gas is another combustible mixture of hydrocarbon gases that occurs with
petroleum deposits consisting primarily of the gas methane. It is found with other fossil
fuels and in coal beds. It is created by the decay of methanogenic organisms in marshes,
bogs, and landfills. Lower temperatures are likely to produce more petroleum, and higher
temperatures are likely to produce more natural gas. Of all the fossil fuels, natural gas is
the least harmful, but it is still harmful and is becoming harder and harder to get to as
easily obtained sources are being depleted, as with all the other fossil fuels.
