front 1 Which energy source is considered nonrenewable? a.Solar b.Nuclear c.Fossil Fuel | back 1 b & c - Nuclear and Fossil Fuel |
front 2 Which is not a fossil fuel energy resource? a.Coal b.Oil c.Uranium | back 2 c - Uranium |
front 3 What is a commercial vs subsistence energy source? | back 3 Commercial= bought and sold to the general public Subsistence= gathered by individuals for their own immediate needs |
front 4 Why is gasoline the fuel of choice for transportation? | back 4 Relatively compact and can be turned on and off quickly. |
front 5 Steps to how electricity is produced from coal? | back 5 Coal is pulverized, burned in a furnace, boils water into high pressure steam, which drives a turbine and spins a generator. |
front 6 What is the fastest growing energy resource in the world today? | back 6 Solar energy |
front 7 How does a hydroelectric dam work? | back 7 A hydroelectric dam stores water in a reservoir, and when the water is released, it flows through turbines that spin and generate electricity. The moving water turns a generator, converting kinetic energy into electrical energy. |
front 8 What is the difference between nonrenewable and renewable energy sources? | back 8 Renewable = replenishable |
front 9 What is cogeneration/ | back 9 The use of a power plant to generate both electricity and useful heat at the same time. (ie. wastewater turned into thermal energy) |
front 10 Steps of a pressurized water nuclear reactor? | back 10 In a pressurized water reactor, nuclear fission heats highly pressurized water in a primary loop, which transfers heat to a second water loop to produce steam. The steam spins a turbine connected to a generator, producing electricity before being cooled and reused. |
front 11 Steps of energy produced from wind turbine? | back 11 Kenetic --> Mechanical --> Electrical |
front 12 What is often used to store wind power? | back 12 Batteries |
front 13 Difference between biomass-fired power plants and traditional fossil-fuel-burning power plants? | back 13 Cost of biomass is much higher |
front 14 What is biomass? | back 14 Taking energy from recently living things that store chemical energy from the sun. |
front 15 What pollutants are most commonly released during the burning of biomass? | back 15 Particulate matter (PM), Carbon monoxide (CO), and Carbon dioxide (CO2) |
front 16 What is used to convert geothermal energy into electricity? | back 16 Groundwater (steam is evaporated and turns turbines) |
front 17 What is a hydrogen-fueled cell? | back 17 A hydrogen fuel cell is an electrochemical device that converts the chemical energy of hydrogen (H2) and oxygen (O2) directly into electricity, heat, and water. |
front 18 What would a hydrogen-fueled cell car emit? | back 18 Water vapor and heat (hydrogen gas is used as a fuel, not a product and carbon dioxide is not emitted either) |
front 19 Steps to transforming energy in hydrogen powered cells? | back 19 Hydrogen reacts with oxygen to produce water. (Hydrogen gas enters the cell and is split into protons and electrons. The electrons flow through an external circuit to generate electricity, while the protons combine with oxygen to form water as a byproduct.) |
