The ultimate source on energy on Earth is the... - Answer sun
energy is always available and there is a tremendous amount. The
challenge is collecting it, concentrating it, and distributing it. - Answer
solar energy
Describe the difference between passive and active solar heating -
Answer Passive solar heating is an old method which does not
require any mechanical devices to collect and distribute heat. it uses
walls. Active solar heating is mostly used for heating water and requires
a system of collectors that absorb solar energy and a system of pumps
and fans to distribute the heat.
,Ancient Greeks and Romans used _______ solar heating. - Answer
passive solar heating
Active solar heating is mostly used for heating ________. - Answer
water
How do photovoltaic solar cells generate electricity? - Answer
When solar energy strikes a PV cell, electrons from the surface layer
(i.e. silicon) atoms jump to an excited state, and flow across a one-way
electrostatic barrier formed by the junction between two different
semiconductor materials such as boron and phosphorus. Wires
connecting the layers allow electrons to return to the surface layer,
creating an electric current.
What renewable energy resources are indirect forms of solar energy? -
Answer biomass energy
What sources of indirect solar energy have humans been using since
living as hunter gatherer societies? - Answer Solid biomass
Provide at least one example of solid biomass AND liquid biomass. -
Answer firewood and ethanol
, How does photosynthesis play a role in our ability to use biomass
energy? - Answer when we burn plants, ethanol, plant and animal
oils or wastes we are releasing chemical energy producing heat like
photosynthesis.
List at least three environmental impacts of using solid biomass for
energy. - Answer deforestation, loss of biodiversity, habitat loss
Provide at least two examples of biofuels.Biofuels are liquid forms of
biomass. - Answer ethanol and biodiesel
_______ is produced through decomposition and mostly consists of
_____. - Answer Biogas, manure and sewage
How is wind energy an indirect form of solar energy? - Answer
atmospheric circulation is driven by temperature
What is a wind farm? Where are the most productive sites to collect
wind energy? - Answer To harvest wind energy, wind turbines are
established in groupings called wind farms. and the best sites are the
great plains.
