MODULE 7 Flashcards
A significant decrease in the supply of energy resources to an economy in a certain time and place
Energy crisis
Key factors that triggered the 2000s energy crisis
Middle East tension, dwindling oil reserves, oil price speculation, and rising energy demand
The price of oil at its peak during the 2000s energy crisis
$147.30 per barrel in 2008
Reasons why there is a need to tap alternative energy sources
Rising fuel prices, depleting fossil fuels, and environmental concerns
Reasons why there is a need to tap alternative energy sources
Rising fuel prices, depleting fossil fuels, and environmental concerns
Energy produced by using potential energy in water to drive turbines and generate power
Hydroelectric energy
One key environmental advantage of hydroelectric power generation
Produces clean energy without chemical processes
Renewable energy source using sunlight to generate electricity or heat water
Solar energy
Main challenge in utilizing solar energy
Tapping solar energy in the most efficient way
Energy generated by harnessing wind power to propel turbine blades attached to electric generators
Wind energy
One advantage of wind energy as a power source
Free and renewable
Energy produced from the waste of human, animal, and agricultural activities
Biomass energy
Key advantage of biomass energy in waste management
Converts biological waste into energy, recycling it effectively
Energy harnessed from the heat within the Earth
Geothermal energy
Advantage of geothermal energy in power generation
Produces no harmful by-products when properly implemented
Energy generated by using the rise and fall of tides to drive turbines in small dams
Tidal energy
A renewable source of power derived from gravitational forces of the sun and moon
Tidal energy
A process producing electricity using the temperature difference between deep cold ocean water and warm tropical surface waters
Ocean Thermal Energy Conversion (OTEC)
A feature of OTEC that provides constant energy output
Baseload electricity (24/7, year-round)
Energy produced by the force of ocean waves used to generate electricity
Wave energy
Energy source tied with biomass, requiring burning for electricity production
Wood energy
Main challenge in large-scale power production from alternative energy sources
Inefficiency compared to conventional energy
Why some countries are hesitant to adopt alternative energy
High costs of decommissioning old systems and setting up new infrastructure
Ideal approach for countries transitioning to alternative energy sources
Shifting in phases
