FREE Agricultural/Bioengineering Renewable Energy Questions and Answers
The energy gained from a raw energy source divided by the energy required to access the source is known as the ____ ratio.
The term "energy yield ratio" refers to the proportion of energy that a system, such as a wind energy conversion system, provides throughout the course of its lifetime to the energy needed to produce it.
Energy Resources are those that have been in use for a long time.
Coal, gasoline, firewood, and other fuels that have been utilized for a long time in this manner are examples of conventional energy sources. In terms of usage, unconventional sources are still very young.
Which of the following claims concerning traditional energy sources is accurate?
Coal, petroleum, natural gas, and other conventional energy sources are substantial contributors to pollution and the thinning of the ozone layer. The reserves of traditional energy sources are finite and will eventually run out. The world's reserves of petroleum, natural gas, and coal are expected to last 50 years, 52.8 years, and 153 years, respectively, at the current pace of consumption. The world's most popular energy source is oil. Currently, oil supplies 31% of the world's energy requirements.
What is the primary issue with wind power?
The primary issue with wind energy is that it needs a lot of acreage. In the same way that it threatens bird habitat, it also endangers other wildlife. It produces energy from wind, making it a renewable source of energy.
Power plants using renewable energy have
Plants that use renewable energy little or never need gasoline to run. They therefore contribute very little to pollution.
The chemical, pharmaceutical, and paint industries all employ _____, a petrochemical, as a raw material.
The chemical, pharmaceutical, and paint industries all use coal as a raw material since it is a valuable petrochemical. From a long-term standpoint, it is crucial to preserve coal for use as a raw resource in the future.
What among the following is to blame for global warming?
Global warming has been caused by the burning of fossil fuels for various industrial and domestic operations over the last 100 to 150 years. The ozone layer suffers when CFCs are released into the atmosphere.
Since the past 150 years, which of the following has contributed to global warming?
Global warming is allegedly being caused by anthropogenic greenhouse gas emissions, particularly as a result of the growth of industry during the past 150 years. emissions of sulfur and aerosols chill the planet.
The rise in global energy demand is caused by ______ .
The need for energy globally has increased dramatically as a result of rising global population. The creation of new industries has increased the world's energy needs in addition to the industries' rapid expansion. These factors make conventional energy sources insufficient, necessitating the use of alternative energy sources.
Which of the following pollutants are released when fossil fuels are burned?
Oxides of Carbon, such as CO and CO2, Oxides of Nitrogen, such as NO and NO2, and Oxides of Sulfur, such as SO2 and SO3, are produced by fossil fuels. Apart from that, fossil fuels also produce heat and particulate particles.
Energy Resources are categorized into ____ based on usefulness.
Energy Resources are divided into Primary, Intermediate, and Secondary Resources based on their usability. Prior to human intervention or modification, primary resources exist in nature. While secondary resources are the type of energy that is ultimately delivered to the customer for use, intermediate resources are received from primary resources after one or more phases of transformation.
The majority of renewable energy sources come from _______ .
The locational specificity of renewable sources is one of their main drawbacks. Hydropower dams cannot be built in states without rivers, while wind energy facilities cannot be built in states with winds that are less than 23 km/h at 50 m altitude. Because they depend on certain geographic conditions, renewable energy sources are not available everywhere. They are diluted, thus they are ineffective. Most renewable energy sources don't need fuel, hence their pollution levels are minimal to low.
Which of the following claims about solar energy is true?
Solar energy is a form of energy that hasn't historically been used and is still being used now. It is therefore an unconventional source of energy. It is a renewable source of energy since it is limitless and unending.
What category of resource is not one of the ones listed below?
Fossil fuels, which are the main energy sources, are the main source of hydrogen. Hydrogen is a secondary source of energy as a result. Since they can be derived directly from nature, crude oil, coal, and sunlight are the main energy sources.
Which of the following describes how hydropower is disadvantageous?
Large areas must be cleared for the construction of hydroelectric dams, which has an impact on the local species. Dams can occasionally produce forest flooding, which harms the forest. The aquatic life is also impacted by dam construction.
Plants that produce renewable energy need _______ than conventional generators.
After installation, renewable energy plants require very minimal maintenance. Compared to conventional fossil fuel generators, they have significantly lower running costs. They only require a tiny quantity of gasoline to operate. They don't use uranium, either.
