- With the transformation of global energy, the development of hybrid energy system of nuclear energy and other clean energy is a new research direction.
- Wood is one of the key renewable resources due to its excellent structure and physical properties.
- Diesel engines are among the most effective engines in the world, however they are also recognized for their traditional smoke and high level of nitrous oxides, Nox, emissions.
- About 39% of total energy in the United States is consumed in residential and commercial buildings and energy usage must be reduced.
- Lower sulphur coal and desulfurization systems are used in coal-fired power plants to reduce emissions of sulfur dioxide (SO2), but their by-products also need to be considered.
- The use of biomass for power generation is increasingly common. However, one of the most important problems when using biomass is the amount of waste produced in the combustion process such as ash, which must be transported to landfills for deposition.
- Alternative forms of heat, such as ground and air, and thermal recycling, are important to develop in order to reduce energy usage.
- With increasing focus on addressing fossil fuel shortage and harmful automotive emissions, there has been a growing interest in hybrid electric and pure electric vehicles.
- Small hydro power is considered environment friendly and sustainable as compared to other renewable sources of energy, but work must be done to optimise its outputs.
- The high energy demand and the threat of climate change have led to a remarkable development of renewable energies, initially through technologies applied to the terrestrial environment and, recently, through the awakening of marine renewable energies.
- The recent transition towards sustainable energy resources, aiming for the decarbonisation of the electrical power sector has gained global and regional importance.
- Improving the energy efficiency of wind turbines and capacity factor of wind farms is necessary to help replace fossil fuel sources with renewables.
- The large-scale generation of electric power using solar energy stimulates the development of novel technologies by researchers with ultimate resource qualities.
- With the increasing penetration of wind power, reliable and cost-effective wind energy production is of more and more importance.
- Frequent escalations in fuel costs, environmental concerns, and the depletion of non-renewable fuel reserves have driven the power industry to significant utilisation of renewable energy resources.
