Offshore wind turbines cost how much more than conventional on land ones?
50% more
wind speeds at sea can be how much greater than on land? what does this translate to in terms of increased energy?
- wind speeds up to X2 as fast
- energy produced up to X5 as much
What do offshore wind farms reduce the problem of?
NIMBYism
Who has complained about offshore wind farms?
Ministry of Defence
argued they interfere with radar so are a threat to national security
UK hopes what fraction of its future energy needs are met by wind?
1/3

No need to cover kilometres of land space
What are the X3 main types of biofuel?
crops
trees
algae
Name X4 challenges needed to solve within the biofuel industry;
- new GM crops to be engineered for fuel not food
- address competition between food crops + fuel crops for agricultural space
- still uncompeititve $$$ wise against fossil fuels
- need to smooth out supply chain to minimise carbon footprint
Between 1996-2006 what happened to hydro power in the UK?
remained fairly constant
Between 1996-2006 what happened to wind and wave energy in the UK?
made the most progress in terms of % of supplying electricity generation
What is the purpose of Carbon Capture Storage
capturing CO2 released by burning coal and burying it underground
Is it the case that HICs have the greatest amount of renewables? Why?
No
due to tech leapfrogging
Tajikistan has what % of its energy from renewables? What is this almost all from?
58% renewables
almost all hydroelectric
Where is investment in terms of % of energy supply in renewables greatest, in HICs or LICs?
in recent years in LICs
In Tajikistan what is the name of a solar water heating system?
Do-It-Yourself Solar Water Heating System
What is the D-I-Y Solar Water Heating System in Tajikistan financed by?
UNDP
How does Tajikistan have the skills for its DIY Solar Water Heating System?
Development of “East2East” programme where exchange on sustainable energy solutions is shared
How does the DIY Solar Heating System in Tajikistan help bridge the development gap?
workshops for local Tajik women on construction and installation of solar heating systems
= earn income generation
= less time searching for firewood to heat water
