| Question | Answer |
|---|---|
| Alternative energy sources that are often called “new renewables” include : | solar,wind,geothermal |
| Witch renewable energy source experienced the most rapid rate of growth from 2010-2015 mostly due to germany and china production- | photovoltaic solar |
| photovoltaic solar technology is best described as- | using solar panels to convert sunlight directly into electricity (does not use heat) |
| CSP (concentrated solar power) technology is best described as - | using mirrors to focus sunlight to make heat, which is then used to make electricity. |
| A solar cooker is an example of - | concentrated solar power |
| solar cooker | A device that uses sunlight to heat or cook food |
| A major obstacle of wind farms near populated and scenic areas is the- | opposition from local residents |
| One benefit of offshore wind farms- | wind speeds are higher and turbulence is lower over water than over land |
| Wind turbines kill more birds that which of the other major causes of bird mortality- | cats, pesticides, towers, collision with windows |
| Wind turbines convert the winds ___ energy into electricity | kinetic |
| What does NIMBY stand for- | not in my back yard |
| An example of NIMBY- | People say they support wind farms, but don’t want one built near their homes. |
| U.s geothermal energy is most available in- | the west |
| Geothermal energy is energy that arises from- | the earth interior |
| What does not originate from sunlight- | geothermal |
| What sources are intermittent - | solar,wind |
| The most widely used source of of renewable energy for generating electricity is- | hydro electric |
| What energy sources do not generate substantial greenhouse gas emissions when used to generate electricity- | wind,solar,nuclear |
| What catastrophic event disabled the emergency power generators at the Fukushima Daiichi nuclear plant in Japan and led to the reactor meltdown- | a tsunami |
| Where is the nuclear waste from nuclear power plants in the united states currently being stored- | on site at nuclear power plants |
| The process used to generate nuclear power is | fission |
| How is energy produced by nuclear fission used to produce electricity- | Nuclear fission produces heat when atoms are split. That heat is used to turn water into steam, and the steam spins a turbine connected to a generator, which makes electricity. |
| What element is the starting material for nuclear fission reactions- | uranium |
| What type of energy is most commonly used in the homes of those living in the poorest nations- | biomass energy |
| What is a drawback associated to the use of biomass energy- | Unstable wood harvesting can lead to deforestation,soil,erosion,and desertification |
| What is an alternative liquid fuel produced from biomass- | ethanol |
| Hydropower uses the ___ energy of flowing water to generate electricity- | kinetic |
| What is a source of biomass energy- | animal waste |
| What is an area where water is stored behind a dam | - reservoir |
| What is the most widely used renewable resource in the world- | hydropower |
| Conventional alternative to fossil fuels | nuclear power, hydropower, biomass energy |
| Top producers of nuclear power - | united states and france |
| Nuclear power incidents- | Three mile island, Pensalvania, chernobyl ukraine, Fukushima japan |
| Bio energy feed stocks - | plant matter, animal waste, trash/landfill |
| Bio mass pros- | renewable/ uses less waste materials |
| ethanol | -Alcohol fuel made from plants like corn. |
| Renewable resource | -Energy sources that can be replaced naturally (like solar, wind, water) |
| Nonrenewable resource- | Energy sources that run out and take millions of years to form (like coal, oil). |
| What type of solar is more common in the united state- | PV |
| What is nuclear power: | Electricity made using energy from nuclear reactions |
| What is nuclear energy: | Energy stored inside the nucleus of atoms |
| What is nuclear fission | : When an atom splits and releases energy/heat |
| What are pros of nuclear power | : Produces lots of electricity, low greenhouse gas emissions, reliable |
| What are cons of nuclear power: | Radioactive waste, expensive plants, risk of accidents |
| What is biomass: | Plant or animal material used for energy |
| What is bioenergy: | Energy made from biomass |
| What is hydropower: | Electricity made from moving water |
| What are pros of hydropower: | Renewable, little pollution, reliable |
| What are cons of hydropower: | Expensive dams, harms ecosystems, floods land |
| What is intermittent: | An energy source that does not work all the time (on/Off) |
| Large-scale solar and wind farms require: | Significant land areas |
| What is solar energy: | Energy from the sun |
| What is wind power | : Energy made from moving air (wind) |
| What are wind turbines: | Machines with blades that spin to make electricity |
| What is geothermal energy: | Energy from heat inside Earth |
| What is offshore wind: | Wind turbines built in the ocean |
| What is onshore wind: | Wind turbines built on land |
| Benefits of wind power: | Renewable, no air pollution during use, low greenhouse gas emissions |
| Benefits of solar power | : Renewable, no air pollution during use, reduces greenhouse gases , uses free sunlight |
