Without conservation, this energy source could cause deforestation
Uses solar photons to knock electrons off a semiconductor to create electricity
Uses the potential energy of stored water from a reservoir to create electricity
When supplies of a particular energy type are limited, it is known as a
Due to the abundance and low cost of this resource, this energy source can provide the greatest amount of electricity in the USA
Tidal power can only be generated
Put the items below in the correct sequence for the generation of electricity using the wind
W – Electricity is transferred to the grid
X – Wind turns the wind turbine blade
Y – The gearbox transfers mechanical energy to the generator
Z – Generator converts mechanical energy into electrical energy
One of the main reasons we do not use photovoltaic cells to generate all our electricity is
A sample of radioactive waste has a half-life of 20 years and an activity level of 2 curies. After how many years will the activity level of this sample be 0.25 curie? (REMEMBER EVERY 1/2 life Divide by 2!)
Also called subsistence energy sources, people gather this energy source for home use in many less developed countires?
A positive of using natural gas as a fuel instead of than oil, is that natural gas
A school is trying to switch to renewable energy to power its area. They decided on photovoltaic panels in the nearby desert. An APES class hypothesized that the shade from the newly installed solar panels will decrease the population of creosote bush, a native desert plant in the area. Before construction begins, what experimental data should the class collect in order to eventually test the hypothesis?
