STUVIA 2024/2025
-already used about half of proven reserves
-remains expected to last 41 years at current rate of consumption - ✔✔expectancy of oil use
-china is the worlds largest producer of wind turbines and second installation after europe
-world's fastest growing energy source
-wind turbines can produce power 90% of the time
-Texas leads US in wind power
-wind power provides local control of energy
drawback: bird and bat mortality
-isssue with storage but power doesn't have to travel far. - ✔✔Wind energy
-CO2, mercury, arsenic, lead and other high levels of pollution - ✔✔coal reacting with water in the
atmosphere produces what effects?
-collect usable heat
-more efficient than photovoltaic
-BUT it varies geographically
-*solar potential in SW US concentrated
--most potential in cold areas, making Colorado (sunny and cold) best. - ✔✔Solar thermal systems
%
-fertility rates
-mortality rates
-life expectancy (huge impact) - ✔✔factors affecting pop growth
-generate electricity directly
-creates electrical currents directly by bumping off electrons
-PV systems are not super efficient because of conversion to a/c power - ✔✔Photovoltaic cells
-shale deposits in 'tight' formations
-mix of water and fluid pumped at high pressure into the rock which releases gas.
-bad: contaminates water wells and creates earthquakes even in places that are not normally
seismically active. - ✔✔Fracking (natural gas)
-should generate energy locally, on demand - ✔✔energy storage and transmission
-smallest and simplest of the hydrocarbons, largely composed of methane
-only produces 1/2 as much co2 as coal (substitution may help global warming)
-more than 1/2 of reserves are in the mid east and russia
-2nd largest commerical fuel
