Energy Process
This energy source uses moving water to spin turbines connected to generators
hydroelectric power
This fossil fuel is considered more efficient than coal because it burns cleaner and produces more energy per unit.
Natural Gas
This renewable energy source has high upfront costs but very low operating costs once installed.
Solar energy
Burning fossil fuels releases this greenhouse gas that contributes to climate change.
What is carbon dioxide (CO₂)?
Solar energy is most available during this time of day.
Daytime
This process involves splitting atoms to release large amounts of heat energy
Nuclear power
Solar panels are less efficient at night because they rely on this energy source.
What is sunlight (solar radiation)?
Fossil fuels like coal are often cheaper upfront because of this existing infrastructure.
Mining and power plant systems
Hydroelectric dams can negatively impact ecosystems by disrupting these natural systems
What are river ecosystems (or fish migration patterns)?
This renewable energy source depends heavily on geographic features like wind patterns.
Wind energy
Solar panels generate electricity by converting sunlight directly into electricity using this effect.
photovoltaic effect
Energy is lost in power plants mostly in the form of this type of energy.
heat
Nuclear energy plants are expensive mainly due to construction, safety systems, and this long-term expense.
What is waste management/storage
This type of pollution is a major concern with nuclear energy if accidents occur
What is radioactive contamination?
Fossil fuels are considered non-renewable because they take this long to form
A human lifetime?
Wind turbines generate electricity by converting this type of energy into mechanical energy first.
What is kinetic energy (of wind)?
how many goals did seth let in at the taff student game?
6?7? too many?
True/False: Sam can do the worm
True
Wind turbines can harm wildlife, especially these flying animals.
What are birds and bats?
What is Mr. Jacksons favourite type of cuisine
Middle Eastern
In geothermal plants, underground heat turns water into steam, which then spins turbines—this heat originates from this source deep inside Earth
What is Earth’s internal heat (from radioactive decay in the mantle/core)?
Combined-cycle power plants improve efficiency by using both gas and steam turbines—this second turbine is powered by waste heat from this component
What is the gas turbine (exhaust heat)?
Although wind energy is free once turbines are built, costs can increase due to this challenge related to inconsistent production.
Backup systems/batteries
Although solar energy is clean during use, environmental concerns arise from this stage involving materials like silicon and rare metals.
What is manufacturing/production of solar panels?
Hydroelectric power availability depends on consistent water flow, which can be affected by this long-term environmental change.
What is drought?
