Abstract This research discusses in details the wave energy which is an interesting non conventional source of energy that helped us a lot through the years to keep up with the challenge of our time. The research starts with introducing a background of that energy as in who, when and how it was first invented and the gradation that happened in the technologies progress in the past. The objectives of the research are then clarified in the sequence of the...

Explore potential renewable energy sources, optimum combinations, and efficiencies Wind Wind power is a method of renewable energy. It uses the wind to turn large blades attached to a rotor. The turbine rotor is attached to a gearbox. This gearbox converts the low speed of the rotor into a high-speed motion. The high-speed shaft is coupled to a generator. An exciter is needed to provide the required excitation to the magnetic coil of the generator so it can generate the...

Air we breathe in consists of molecules. Even the tiniest of regions of air will contain millions and millions of molecules. These molecules are in constant motion, traveling randomly and at great speed. There is a constant bombardment with each other and every other object that is in contact with the air. One interesting thing about air is that it is a medium through which heat or sound travels. But our current main attention will be on sound. Sound is...

The world has been powered by carbon-based energy since the industrial revolution. It is what humans know as convenient, reliable, and cheap. However, the environment is slowly paying the price for the use of these fossil fuels. A change needs to occur, and a willingness to switch to renewable energy is the only way to ensure the planet will remain intact. Humans are at fault here, deciding to burn limited resources when there is an alternative way to produce clean...

Biomass is any waste, wood or crops that can be used as an alternative energy source to fossil fuels. Examples of biomass are bacterial decay, burning, fermentation and conversion. Burning is the earliest form of biomass, it was used up until the 1800’s and was used to heat up houses. Bacterial decay is when bacteria feed on dead organisms and create a gas called methane, this gas can be very bad for our environment by producing excess carbon dioxide or...

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 2050, it is projected that the region will be able to generate 49.97507GW of non-renewable energy and 708.5722GW of renewable...

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 outlined specific targets to facilitate the shift towards decarbonisation. The Scottish Energy System Strategy states that renewable sources will supply...

Energy demand is required to improve people’s health, welfare, and meeting economic and social development is on the rise each day. All societies in the world need a form of power to support basic human essentials such as cooking, lighting, communication, mobility, and space comfort (Gielen et al. 2020). Fossils including oil, gas, and coal have been the most dominant source of fuel since 1850. These conventional sources have an adverse environmental impact on the environment because it emits excess...

Solar energy is the green source with the widest potential and plays a vital role in developing energy all over the world. Human beings have been making use of solar energy as early as 7th century. Later on, due to the advancements in science and discoveries of alternative sources of energies - mostly non-renewable and fossil fuels, use of solar energy was found to be expensive and had comparatively poor performance than other energy sources. Since then more usage of...
