Solar Energy

How does solar energy transform? The source of Earths solar power is the Sun. solar energy is made up of radiant light and heat which is harnessed using a range of ever evolving technologies. These include: • Solar heating • Photovoltaics • Solar thermal energy • Solar architecture • Molten salt powerplants • Artificial photosynthesis

Passive solar techniques • Orienting a building to the Sun • Selecting materials with favourable thermal mass • Light dispersing properties • Designing spaces that naturally circulate air Active solar techniques • The use of photovoltaic systems • Concentrated solar power • Solar water heating All of the above harness the energy

Continued… It is an essential source of renewable energy and its technologies are categorised as either passive solar or active solar.

Pros • Large magnitude available • Huge long term benefits • Will increase countries energy • Reduce pollution • Lower the costs of mitigating global warming • Enhance sustainability Pros and Cons • Cloud coverage • Isolation • Sunlight absorbs in water 71% of the globe is made of water • Land available to humans • Time variation i. e. night time

How will it help people? • Due to the large magnitude of solar energy available it is a highly appealing source of electricity. • Its is affordable inexhaustible and has huge long term benefits and there for will increase countries energy security through reliance on fossil fuels.

How I use my own Energy to help others. I try to help my parents around the house by doing my fair share of the household chores. I also enjoy spending time with my little brother so I read & play with him when my mam and dad need to do other things.
