Renewable –vs‐ NonrenewableResources

Energy Sources – Renewable andNonrenewable Resources Renewable can be replenished fairly easily– Renewable Energy Derived from resources likethe sun and wind, that can easily be replenished Non‐renewable can not be replenished (orat least not in our life time)– Non‐renewable Energy energy sources like coaland oil, that can not be replaced over a usefulperiod of time.

Renewable Energy/Resources

Biomass ‐ organic material made fromplants and animals (microorganisms).Pros: Cleaner burning than oil Abundant renewableCons: Causes food prices to risebecause we use grains tomake ethanol Greenhouse gas producer Not efficient to transportthe raw material

Geothermal ‐ Temperatures hotter than the sun'ssurface are continuously produced inside the Earth by the slowdecay of radioactive particles, a process that happens in all rocks.Pros: Low greenhouse gasproducer Renewable in some places Energy and cost efficientCons: Few geothermal fields thatare not on protected land

Hydropower ‐ energy from moving waterPros: No greenhouse gases Can generate lots ofelectricity RenewableCons: Can damage environment wheredam is built (can change the natural watertemperatures, chemistry, flow characteristics, andsilt loads, all of which can lead to significantchanges in the ecology (living organisms and theenvironment) and rocks and land forms of theriver upstream and downstream. Expensive to build

Solar Power ‐ the sun’s rays (solar radiation) thatreach the Earth. This energy can be converted intoother forms of energy, such as heat and electricity.Pros: No greenhouse gasesreleased When located on buildingshave limited impact onenvironment RenewableCons: Expensive investment toinstall Not effective in areas withlimited light

Wind Power ‐ wind turbines use blades, the wind flows overthe blades creating lift, like the effect on airplane wings, which causesthem to turn. The blades are connected to a drive shaft that turns anelectric generator to produce electricity.Pros: No greenhouse gasesproduced Renewable in some places Cons:Limited to areas of reliablehigh windsHigh initial cost (but not asmuch as solar)Extensive land useHarms bats and migratingbirds

Non‐Renewable Energy/Resources

Oil (Petroleum) ‐ Crude oil is a smelly, yellow‐to‐blackliquid and is usually found in underground areas called reservoirs.Pros: Easy to produce andtransport High energy output Cons:Non‐renewableRegion specific (causes lots of wars)Running outEnvironmental damage from spillsHigh greenhouse gas (CO2)producer

Natural Gas ‐ main ingredient in natural gas is methane,a gas (or compound) composed of one carbon atom and fourhydrogen atoms.Pros:Cons: Expensive to transport Abundant Fewer greenhouse gases Greenhouse gas producer Non‐renewablethan coal or oil Many of the areas that are now beingexplored and developed for natural gasproduction are wilderness areas, anddevelopment of these areas have largeimpacts on the area's environment,wildlife populations.

Coal ‐ a combustible black or brownish‐black sedimentary rock composedmostly of carbon and hydrocarbons. Most abundant fossil fuel produced in the U.S.The energy in coal comes from the energy stored by plants that lived hundreds ofmillions of years ago, when the Earth was partly covered with swampy forests.Pros: Abundant High energy outputCons: Non‐renewable (it takesmillions of years to create) Extraction is destructive toenvironment High greenhouse gas producer

Nuclear Power/Uranium ‐ nuclear fission, atoms aresplit apart to form smaller atoms, releasing energy. Nuclear power plants usethis energy to produce electricity.Pros: No greenhouse gases Very efficient energyproducer abundant Cons:Expensive to build and maintainreactorsProduces radioactive wasteDifficult to dispose of wasteHeated waste water is harmful toaquatic lifeTerrorism threat with spent fuel(nuclear weapons)

Nonrenewable Energy Chapter 15 15-1 What Major Sources of Energy Do We Use?! Concept 15-1A About three-quarters of the worldʼs commercial energy comes from nonrenewable fossil fuels and the rest comes from nonrenewable nuclear fuel and renewable sources. ! Concept 15-1B Net energy is the amount of high-quality usable energy available from a

As the technology improves and more people use renewable energy, the prices may come down. At the same time, as we use up fossil fuels such as coal, oil, and natural gas, these nonrenewable resources will become more expensive. At some point, even if renewable energy costs are high, nonrenewable energy will be even more expensive.

knowledge of renewable and non-renewable energy (Table 1). Questions were taken or modified from the natural resources test in the Columbus, Ohio Public Schools Grade 5 Science Curriculum Guide (CCSSD, 2005). These questions centered on identifying the students' abilities to distinguish the difference between renewable and nonrenewable resources.

4. What is the difference between renewable and nonrenewable resources? Provide examples of each. Answer: Renewable resources include the sun and wind and are things that can be "replenished" or are not used up. Nonrenewable resources include fossil fuels like coal and oil that took a long time to form and are not as easily replenished.

world's commercial energy comes from nonrenewable fossil fuels and the rest comes from nonrenewable nuclear fuel and renewable sources. Concept 15-1B Net energy is the amount of high-quality usable energy available from a resource after the amount of energy needed to make it available is subtracted.

Resources and Scarcity 6 Slide 8 The Move toward Renewable Energy The United States has been from nonrenewable to renewable resources. Renewable energy use is . Renewable energy makes up about 9 percent of energy used. Scarcity Scarcity is the idea that all resources are . Resources cannot fulfill unlimited wants and needs.

Reuse bags and recycle them.) 4. Pass out the “Renewable or Nonrenewable” worksheet, assign students to name one item from each of the four categories (fossil fuels, minerals, plants and animals) and explain how they can conserve the natural resources. Final Assessment Idea H
