New Technologies and Energy
- Fossil Fuels
  - Gasification of coal underground - reaches deep, thin or fractured deposits
    - Able to create immediate and storable fuel
    - By-products can be used in other industries
    - Expensive
    - Releases more greenhouse gases e.g. methane
  - Secondary crude oil recovery (pumping natural gas)
  - Tertiary crude oil recovery (solvents, steam and detergent)
  - Fracking of natural gas and oil from shale rock by drilling and using a high-pressure water mixture
    - Releases carbon dioxide
    - Makes UK less dependant on other countries
    - Allows otherwise unexploited reserves to be reached
    - Cheaper gas and oil prices
    - Chemicals poison groundwater
    - High volume of water needed
    - Earthquakes and subsidence
    - Land-rights issues - drilling under private land
    - Distracts concerns from renewables
- Nuclear Power
  - Fissile fuels (able to sustain chain reactions) e.g. plutonium 239
  - Nuclear fusion being developed
- Renewable Energy Resources
  - Parabolic reflectors - reflects light to single point (solar)
  - Heliostats - tracks sun to get maximum light (solar)
  - Oscillating water column - generates electricity through changes in air pressure caused by tides (tidal)
  - Pelamis - sections of the machine bend in water and movement is converted to energy (tidal)
  - In-stream tidal turbines - tides turn blades of a turbine to power generator (tidal)
  - Gallium arsenide cells instead of silicon (solar)

It is a great diagram and informative. It is very important to know about the new technologies and emerging energies. The diagram is going to help a lot of the fresh and new graduate CV writing services companies which are planning to extend their business or open branches of the startups in many places. This diagram will be helpful to those who are planning to initiate their businesses and startups.
