Some energy resources are non-renewable resources. These are resources that can never be replaced or are replaced more slowly than they are used. Oil, natural gas, and coal are non-renewable resources called fossil fuels. Fossil fuels are energy resources that formed from buried plants and animals that lived a very long time ago. Millions of years ago, the plants stored energy from the sun by photosynthesis. The animals stored and ate the energy from the plants. When we burn fossil fuels today, we are using the sun’s energy from millions of years ago. Where did the energy contained in fossil fuels come from? _____________________ _____________________ _____________________ USES OF FOSSIL FUELS All fossil fuels have stored energy from the sun. This can be changed into other kinds of energy. The figure below shows how we use fossil fuels. The three most common fossil fuels are coal, natural gas, and oil (petroleum). Burning coal is a way to produce electrical energy. Gasoline, wax, and plastics are made from petroleum. Natural gas is often used to heat homes. NUCLEAR ENERGY Electrical energy is also produced from nuclear energy. Nuclear energy comes from radioactive elements like uranium. The nucleus of a uranium atom splits into two smaller nuclei in a process called nuclear fission. There is not a large supply of radioactive elements, so nuclear energy is a nonrenewable resource. 2 Grade 9 Science Related Reading/Chemistry Children Are Likely to Suffer Most from Our Fossil Fuel Addiction By: Frederica P. Perera Environmental Health Perspective The periods of fetal and child development arguably represent the stages of greatest vulnerability to the dual impacts of fossil fuel combustion: the multiple toxic effects of emitted pollutants (polycyclic aromatic hydrocarbons, particles, sulfur oxides, nitrogen oxides, metals) and the broad health impacts of global climate change attributable in large part to carbon dioxide released by fossil fuel burning. Current scientific evidence indicating that the fetus and young child are at heightened risk of developmental impairment, lower birth weight, deficits in lung function, respiratory symptoms, childhood asthma, developmental disorders, and cancer from fossil fuel pollutants and from the predicted effects of climate disruption such as heat waves, flooding, infectious disease, malnutrition, and trauma. Increased risk during early development derives from the inherently greater biologic vulnerability of the developing fetus and child and from their long future lifetime, during which early insults can potentially manifest as adult as well as childhood disease. Recent reports conclude that reducing dependence on fossil fuel and promoting clean and sustainable energy is economically feasible. Although much has been written separately about the toxicity of fossil fuel burning emissions and the effects of climate change on health, these two faces of the problem have not been viewed together with a focus on the developing fetus and child. These health effects represent a major societal and public health burden. A significant proportion of children 6–17 years of age are reported to have developmental problems including learning disabilities (11.5%), attention-deficit/hyperactivity disorder (8.8%), and behavioral problems (6.3%).Adolescence and old age are also periods of vulnerability, but the potential for both immediate and long-term adverse effects is greatest when exposure occurs prenatally or in the early years. Consideration of the full spectrum of health risks to children from fossil fuel combustion underscores the urgent need for environmental and energy policies to reduce fossil fuel dependence and maximize the health benefits to this susceptible population. We do not have to leave our children a double legacy of ill health and ecologic disaster. 3 Grade 9 Science Related Reading/Chemistry Task 3 – Post Reading Activity Q1: Why can it be said that the energy from burning fossil fuels ultimately comes from the sun? _________________________________________________________________________________ _________________________________________________________________________________ Q2: What are the three most common fossil fuels? _________________________________________________________________________________ _________________________________________________________________________________ Q3: Name three products that come from petroleum. __________________________________________________________________________________ __________________________________________________________________________________ Q4: Write two uses of natural gas. __________________________________________________________________________________ __________________________________________________________________________________ Q5: Write some disadvantages of fossil fuels. __________________________________________________________________________________ __________________________________________________________________________________ Q6: Read the words in the box.
