Coal is the main resource used for energy supply in China by a staggering 63.4% compared to 6.9% hydroelectricity (China Today, 2005). Coal use in Australia is significantly less than this with only 42% of its energy source being coal (Metcalfe, 2007). China has overwhelming carbon dioxide...
The use of non-renewable energy sources is a significant contributor to climate change, which is already having devastating effects on our planet. When we burn fossil fuels like coal, oil, and gas, we release large amounts of carbon dioxide and other greenhouse gases into the atmosphere. These...
In biomass or coal plants, for example, the fuel source is ignited to create steam, which in turn passes through a turbine and generates the electricity. However, increasing fuel costs means operators are looking for alternative fuels which sometimes do not burn as cleanly within the...
It is the first time countries have agreed to move away from fossil fuels. But more than 100 nations had argued for a "phase out" of oil, gas and coal use and some of criticised the deal as not being tough enough. Here are the main criticisms of the ag...
Do some studying every day, even on weekends and when there is no homework assignment. Work through your exercises as they are assigned, rather than doing them at the last possible minute. Exercises do little good if they don’t have time to sink in.Finally,find the best time of day to...
Renewable energy is increasing in use. Renewable energy comes from ubiquitous resources like sun, wind and water. These types of resources are infinite, meaning they are unending. Resources like coal, natural gas, and oil are finite resources, in that, we can use them up, and once they are...
Price parity achieved by renewables is also resulting in the steady displacement of coal power generation from the grid. This increased contribution of variable renewable generation, along with inadequate ancillary support like energy storage, has also increased cycling of large-scale co...
Why is ethanol produced from corn not necessarily a sustainable option as a source of energy? Explain.Biofuels:Biofuels are types of fuels that are produced from biomass instead of from geological processes such as oil. Biofuels are considered a renewable source ...
While developed countries like the USA have made renewable a household name, people in developing countries are also feeling the need to switch from finite energy sources like coal and petroleum. Hence, launching an online green energy product store makes perfect sense. ...
