Our natural resources are coming under increasing pressure with the need for energy production. What
approach can be taken to tackle this global issue?

Solar

Strengths - Free Energy, Reduced Cost, Stable Cost

Weaknesses - Unusable on cloudy days or at night - Requires large area

Opportunities - Sunny areas such as Middle East or Africa receive much light

Threats - Unreliable due to sun exposure

Wind

Strengths - Efficient energy conversion rate

Weaknesses - Noisy and not aesthetically pleasing, Requires remote areas

Opportunities - Much wind out at sea, coastal locations are remote and have strong winds

Threats - Unpredictable weather can cause lack of power

Tidal

Strengths - Very predictable, Cheap maintenance, Reliable

Weaknesses - Can effect the ecosystem, Expensive installation, Energy output sometimes doesn't match demand

Opportunities - Anywhere coastal can install to gain energy

Threats - Scarcity of suitable location

Geo-Thermal

Strengths - Always Available, Low maintenance, Silent

Weaknesses - Location restricted, Some emissions but lower then FF

Opportunities - Volcanoes can be used to gain energy like in Iceland

Threats - An eruption would cause the loss of all materials and would be expensive

Hydropower

Strengths - Flood control, Clean water, Irrigation support, Can begin energy generation instantly, Affordable, Enormous energy

Weaknesses - Major environmental impact, Displaces people, Relocates the water from dam to downstream source

Opportunities - Existing dams and bridges can be turned into hydropower stations reducing cost

Threats - Dam failure can be fatal and destructive, Droughts can make hydropower ineffective

Crude Oil (Multiple types)

Strengths - Cheap, High density energy, Allows for economies to grow, Used to create plastics through cracking

Weaknesses - Major greenhouse gas emissions, Not a renewable source of energy

Opportunities - Used to make plastics, power cars, and heat homes

Threats - Possible to run out of oil or for there to be a shortage meaning energy prices rise
