Transcript of Renewable and Nonrenewable Resources

How to figure it all out
Nonrenewable Resources

Now to release 3.6 MJ from coal at an average 40% efficiency and 25 MJ / kilogram the answer is (3.6 / (25 x 0.4)) 0.36 kg of coal

.36 * 940 kilowatthours =338.4kg/kwh

338.4kg/kwh to lbs = 746lbs/kwh
The Product
Energy Use
In 2011, the average annual electricity consumption for a U.S. residential utility customer was 11,280 kWh, an average of 940 kilowatthours (kWh) per month. That is approximately 746lb of coal.
Reclamation is another way of saying reclaim or restoration. There are several different ways this is done, but most often it is associated with land.
Humans use large amounts of energy everyday. The energy we use comes from resources found in the environment. Humans' choices and use of energy resources affect the environment, or surroundings, of all living things.
Did you Know?
Conservation is the careful use and management of natural resources. It is imperative that we conserve our energy because the majority of what we use is running out.
Can you think of any ways to conserve energy at home?
Ways to conserve Energy
Natural Resources are materials or substances such as minerals, forests, water, and fertile land that occur in nature and can be used for energy and food.
Natural Resources
There are two types of resources; renewable and nonrenewable.
Renewable resources are those that can be replaced or reused. Nonrenewable are the opposite; they cannot be replaced.
Resource Types
Renewable resources are also called perpetual resources. Examples are wind, sun, geothermal, biomass, and water. These resources are more specifically called inexhaustible resources because they will never run out.
Renewable Resources
Renewable Resources Explained
Fossil fuels are a source of energy that formed from the remains of organisms that lived millions of years ago.
Fossil Fuels
What ways can you conserve energy at home?
What about here
Something that can be used to support or help those using it.
What in this picture is a resource?
Biomass is energy from the burning of plants
Not all renewable resources stay renewable. What I mean is this: Renewable resources include all sources that can provide energy without being depleted, as long as they are not used more quickly than they can regenerate.
Can you think of a renewable resource that fits into this category??
What example of nonrenewable resources are being used in this picture?
Energy is measured in Joules and a watt is 1 joule per second so one kilowatt-hour = 1000 x 60 x 60 joules = 3,600,000 j or 3.6 Megajoules 3.6MJ
How do you think reclamation can work in a water environment?
What natural resources can you think of?
Geothermal is energy created by the heat from the center of the earth.
Solar energy is energy from the sun.
hydroelectric energy is created from moving water.
Nuclear energy is created from the destruction of uranium atoms to creates steam turning a turbine.
Wind energy is energy from moving air; wind.
