Kindness is described as being helpful, thoughtful, caring, compassionate, and considerate.
December is the perfect month to show kindness to your fellow human beings, as well as all of the
animals, plants, and natural resources on our planet.
Activity 1: Power to the People
Background: Where do we get our energy in Florida?
This activity will let your students:

Investigate sources of energy in the state

Discuss their efficiency

Examine how energy production contributes to the greenhouse gases (carbon dioxide, methane,
nitrous oxide, etc.) that cause human-induced climate change.
Florida’s sources of power include:
Fossil fuel power
In a fossil fuel power plant, thermal/heat energy produced from burning the fuel (coal, natural gas, or
petroleum) is converted to mechanical energy. Usually a turbine does this and then that mechanical
energy is converted to electrical energy via a generator. Fossil fuel energy is inexpensive to produce
when you compare the amount of energy that is created to the cost of the fuel. However, there are
negative aspects of using fossil fuels. Burning fossil fuels creates pollution that can contribute to
smog, acid rain, and global climate change. Also, to obtain the fossil fuels, we have to destroy portions
of our environment and disrupt landscapes. An example would be strip mining for coal.
Nuclear power
Nuclear energy is produced from controlled nuclear reactions. The most common method today uses
nuclear fission, the splitting of an atom into separate parts. Many
people consider nuclear power a “clean solution” to the energy
crisis. However, pollution from nuclear power includes radioactive
nuclear waste.
Solar energy comes from the sun. Using solar panels or other
technologies, the sun’s rays are converted to electrical energy.
Atmospheric conditions and the solar panels’ positions on the earth
relative to the sun can affect the amount of solar power collected.
Wind energy generates electricity from the wind. Wind energy reduces greenhouse gas emissions
when it offsets, or takes the place of, a fossil fuel power plant. Wind energy’s negative environmental
impacts can include impacts on migrating birds or bats and aesthetic impacts on neighbors.
Bio-fuels/Biomass are solids, liquids, or gases from recently dead biological materials, most
commonly plants. Biomass refers more specifically to the solids from recently dead biological
materials. Firewood is an example of biomass used for energy. Fuel from sugar crops or starch crops
(corn) is called ethanol; fuel from non-edible plant sources like wood or grass is chemically identical
but called cellulosic ethanol. Ethanol is used as a supplement to gasoline in cars. Vegetable oil can
be used as a fuel, but usually just in cars with older diesel engines under specific climate conditions.
While burning biomass and bio-fuels does produce some air pollution, it has less impact on climate
change than burning fossil fuels because of its shorter carbon cycle. Fossil fuels are made from plants
and animals that have been dead and stored underground for many millennia, thus the name “fossil”
fuel. Without human intervention, fossil fuels would continue to store carbon, preventing it from
entering our atmosphere. Plants grown for biomass are active components of the carbon cycle, taking
up carbon while growing and releasing carbon when burned or decomposed. Unlike fossil fuels, biofuels can be re-grown quickly, providing food (corn and sugar) and timber and taking up CO2 (a major
greenhouse gas).
Activity:
1. Begin class in the dark today. If possible, close blinds and turn off lights. Ask students if they
know where their electricity comes from. Is it from a coal-fired power plant? Solar energy? Is the
plant nearby? Have this discussion in the dark.
2. Turn on the lights and point out the ease with which the room was supplied electricity. Where does

the power originate? Explain that students will investigate this today in class.
Divide students into groups of three and verbally tell them the worksheet questions found below.
Assign groups a power plant in Florida to investigate. If you do not have power plant information,
allow students to use the internet. Students will work together to research sources of Florida’s
electricity and electricity’s influence on climate change in Florida. The US Energy Information
Administration and Florida Power & Light are good resources.
When groups are finished, discuss their findings. Review percentages of energy source use and
ask students to make hypotheses regarding the breakdown of use. Do the energy production
resources need to be nearby?
Discuss how power plants affect climate change in Florida. Keep in mind topics such as beach
erosion, threatened species, tourism, the Everglades, and saltwater intrusion.
Turn off the lights again. Ask students to think about worldwide energy usage and the climate
change impacts of that energy use. When you turn them back on and, if time allows, have a brief
discussion.
Discussion Questions
 Why do you think power plants are located in certain areas of Florida? Availability of resources?
Socio-economic factors? Population density? Transportation patterns?
 How efficient are these sources of energy?
 In what way do they affect Florida’s environment?
 How are these sources of energy linked to climate change?
 What are some ways that you can conserve energy?
Worksheet Questions
1. What is the name of the power plant you are researching?
2. Where is the power plant located in Florida? List town/city and two nearby towns/cities.
3. What kind of energy source does your power plant use? Where is the source of the power plant’s
fuel?
4. What types of emissions come from this power plant and how do they affect climate change?
5. Does the power company offer renewable energy? If yes, what types?
6. What three energy-saving actions are you most likely to take?

Activity 2: Energy Efficiency Reading Comprehension
Read the following information to the class about energy, energy sources, and energy conservation.
Afterwards, have a group discussion about conserving energy. Have the student’s think of as many
renewable and non-renewable energy sources as they can and make a list. Ask students for
suggestions on how to save energy and how they feel energy consumption will change in the future.
Then have the students write a brief essay about energy. Topics may include types of energy
available today in the United States, trends for the future, history of electricity, and a comparison on
prices of utilizing various energy sources. Students should make use of the internet as well as library
books, newspapers, and magazines for informational sources on energy.
Energy comes in many different forms. Some sources of energy are
renewable, meaning they can be replenished in a short period of time,
while others are non-renewable sources. These come out of the
ground as liquids, gases, and solids. Besides renewable and nonrenewable energy, there is also electricity. Electricity is the flow of
electrical power or charge. It is a secondary energy source, which
means that it is formed by the conversion of other sources of energy.
These include coal, natural gas, oil, nuclear power, and other natural
sources, which are called primary sources. The energy sources we
use to make electricity can be renewable or non-renewable, but electricity itself is neither renewable
nor non-renewable.
Coal is the largest single primary source of energy used to generate electricity in the United States. In
2003, more than half (51%) of the country's 3.9 trillion kilowatt hours of electricity used coal as its
source of energy. Unfortunately, coal is also a major source of pollution. Burning coal is a leading
source of smog, acid rain, global warming, and toxic air pollutants. In an average year, a typical coal
plant generates:





3,700,000 tons of carbon dioxide (CO2), the primary human source of global warming--as much
carbon dioxide as cutting down 161 million trees
10,000 tons of sulfur dioxide (SO2), which causes acid rain that damages forests, lakes, and
buildings, and forms small airborne particles that can penetrate deep into lungs
500 tons of small airborne particles, which can cause chronic bronchitis, aggravated asthma, and
premature death, as well as haze which obstructs visibility
10,200 tons of oxides of nitrogen (NOx), as much as would be emitted by half a million late-model
cars. NOx leads to the formation of ozone (smog) which inflames the lungs, burning through lung
tissue making people more susceptible to respiratory illness
720 tons of carbon monoxide (CO), which causes headaches and places additional stress on
people with heart disease
Other sources of energy include nuclear power, hydropower, geothermal, solar, and wind power. Like
all industrial processes, nuclear power generation has by-product waste: radioactive waste and heat.
Because nuclear generated electricity does not emit carbon dioxide into the atmosphere, nuclear
power plants in the U.S. prevent emissions of about 697 million metric tons of carbon dioxide. This is
nearly as much carbon dioxide as is released from all U.S. passenger cars combined. However,
radioactive waste is the principal environmental concern for nuclear power. Most nuclear waste is
clothing, tools, and disposable items that have been contaminated with low levels of radioactive dust or
particles. These materials are subject to special regulations that govern their storage so they will not
come in contact with the outside environment.
Of the renewable energy sources that generate electricity, hydropower is the most often used. It
accounted for 7 percent of total U.S. electricity generation and 75 percent of generation from
renewable sources in 2004.
Solar energy can be converted directly or indirectly into other forms of energy, such as heat and
electricity. The major drawbacks of solar energy are: (1) the intermittent and variable manner in which
it arrives at the earth's surface and (2) the large area required to collect it at a useful rate. Solar
energy is used for heating water for domestic use, space heating of buildings, drying agricultural
products, and generating electrical energy.
Like old fashioned windmills, today’s wind machines use blades to collect the wind’s kinetic energy.
The wind flows over the airfoil shaped blades causing lift, like the effect on airplane wings, causing
them to turn. The blades are connected to a drive shaft that turns an electric generator to produce
electricity.
