The document discusses various types of renewable and non-renewable energy resources. Renewable resources include solar, wind, hydroelectric, geothermal, and biomass energies. Non-renewable resources are finite and being depleted, such as fossil fuels like coal, oil, and natural gas, as well as nuclear materials like uranium. Proper management of these resources can help ensure availability for future generations through strategies like improving efficiency and adjusting operations to purchase energy at lower prices.

2. The environment is something you are very familiar with.
It's everything that makes up our surroundings and affects our
ability to live on the earth—the air we breathe, the water that
covers most of the earth's surface, the plants and animals
around us, and much more.

3. Environmental resource management is the management of the
interaction and impact of human societies on the environment
. Environmental resources management aims to ensure
that ecosystem services are protected and maintained for future
human generations, and also maintain ecosystem integrity through
considering ethical, economic, and scientific (ecological) variables

6. • Currently largest source of
electricity from renewables.
• Needs guaranteed supply of
water.
• Cheap to operate
• Reservoirs have multiple uses
Flood control, drinking
water, aquaculture,
recreation
• Kinetic energy of water
rotates turbines which
generate electricity.

7. Solar energy is the most
widely available resource
on the Earth.
In an hour the surface
of the Earth
receives nearly the same
amount
of energy that the whole
humanity
consumes in a year.

8. • How it works
– Wind turbines directly generate
electricity
– Quite efficient (not a heat engine)
• Advantages
– High net energy yield
– Renewable and free
– Very clean source of energy
• No pollution (air or water) during operation
– Long operating life
– Low operating/maintenance costs
– Can be quickly built; not too expensive
– Land can be used for other purposes
• Can combine wind and agricultural farms

10. What is it?
Biomass energy is the use of living and recently dead biological
material as an energy source
Ultimately dependent on the capture of solar energy and
conversion to a chemical (carbohydrate) fuel
Theoretically it is a carbon neutral and renewable source
of energy
Biomass is the biologically degradable part of
waste and residue (including plant matter and animal waste)
of agriculture, forestry and related industries, as well as the
biologically degradable part of industrial and
household waste.

11. Heat in the interior of the
Earth originated during the
evolution
of our planet, and it is being
constantly replenished
by the decay of radioactive
elements
The use of geothermal
energy is particularly
topical in geologically
favorable areas, mainly at
the tectonic
boundaries of plates (for
example, in Iceland).

13. A non-renewable resource is a natural resource which
cannot be reproduced, grown, generated, or used on
a scale which can sustain its consumption rate, once
depleted there is no more available for future needs.
Also considered non-renewable are resources that
are consumed much faster than nature can create
them.
Fossil fuels (such as coal, petroleum, and natural gas),
nuclear power (uranium) and certain aquifers are
examples. Metals are prime examples of non-
renewable resources. In contrast, resources such as
timber (when harvested sustainably) are considered
renewable resources.

15. Crude oil --- is the only nonrenewable
resource in fluid form. A fossil fuel that is
being used up faster than new reserves are
discovered
the oil supply may only last through the
middle of this century. Industrial nations,
with the U.S. far in the lead, are the
biggest consumers of crude oil.
Gasoline, heating oil, and diesel fuel are
the primary uses of the resource, although
manufacturers utilize oil as the base for
such products as plastics and industrial
chemicals
11/13/2017 15

16. Natural gas is primarily composed of
methane, but contains ethane,
propane and butane.
petroleum gas (LPG), a household and
industrial fuel. Consumers use it as a
cooking fuel, for heating and sometimes
for vehicle fuel. According to the current
usage statistics and the volume of
world reserves, the supply of natural
gas should last another century.
Natural gas reserves often share space
with underground oil reserves, so the two
nonrenewable resources are often
extracted at the same time.
11/13/2017 16

17. Coal reserves represent the largest
stockpile of nonrenewable resources
in the world. Coal is the product of
millions of years of pressure on original
organic matter from plants buried
underground.
Bituminous coal, which is the type
most commonly found in U.S.
reserves, is approximately 85 percent
carbon and 3 percent water.
The global supply of coal, given the
current rate at which it is used, should
last at least two more centuries.

18. Uranium is a radioactive
chemical element that naturally
occurs in some groundwater, soil
and rock. Uranium was deposited
in the earth from extraterrestrial
events, probably super novae,
that occurred billions of years in
the past.
Worldwide uranium reserves are
more abundant than mercury,
cadmium, and silver reserves.
However, U-235, the fuel used in
nuclear plants, is very rare.

19. A mineral is a naturally
occurring solid chemical
substance formed through
biogeochemical processes, having
characteristic chemical composition,
highly ordered atomic structure, and
specific physical properties.
By comparison, a rock is an
aggregate of minerals and/or
mineraloids and does not have a
specific chemical composition.
The study of minerals is called
mineralogy.

20. •Diesel fuel in general is any
liquid fuel used in diesel engines. The
most common is a specific fractional
distillate of petroleum fuel oil, but
alternatives that are not derived from
petroleum, such as biodiesel, biomass to
liquid (BTL) or gas to liquid (GTL) diesel,
are increasingly being developed and
adopted.
•To distinguish these types, petroleum-
derived diesel is increasingly called
petrodiesel. Ultra-low-sulfur diesel
(ULSD) is a standard for defining diesel
fuel with substantially
•As of 2007, almost all diesel fuel available
in the United States of America, Canada
and Europe is the ULSD type.11/13/2017 20
