According to Ritchie (2019), Oceania emits 1.3 billion tonnes of CO2 yearly, which is equivalent to 1.3% of the global emissions. Wang et al. (2011) argue that most of the carbon emissions are as a result of the generation of non-renewable energy. From figure 8, in 2016, Oceania generated 227.7412GW of non-renewable energy and 67.29998GW of renewable energy. But, in...

The Scottish Government recognises the need to transition to a low-carbon economy. Current targets aim for the near-complete decarbonisation of Scottish energy by the year 2050 (Scottish Government, 2017). Renewable energy sources are a vital component of this plan and sufficient investment is needed to ensure adequate supplies of renewable energy are available to accommodate this transition. The Government has...

Introduction As the global community grapples with environmental degradation and climate change, the shift towards renewable energy becomes imperative. Renewable energy, derived from natural processes that are replenished constantly, includes solar, wind, geothermal, and hydroelectric power. These energy sources present a promising alternative to fossil fuels, which are finite and environmentally damaging. According to the International Energy Agency (IEA), global...
