What is energy? Energy is something which every human needs for doing almost every function. The two types of energies are stored energy and working energy. It comes in different forms like heat, light, chemical, electrical, nuclear energy etc. There are two sources of energy: Conventional sources of energy (non-renewable): Conventional sources of energy are non-renewable sources which are being used since a long time for many reasons in many places. They are non-renewable because they keep on depleting and cannot be renewed again. Their consumption time is faster than creation time. “FOSSIL FUELS” Fossil fuels are made of dead remains of living organisms. There are three types of fossil fuels; coal, oil and natural gas. 1). Coal: Coal is the most …show more content…
Natural gas emits some of green house gases too like carbon dioxide which cause change in climate and cause global warming. Non-conventional energy source (renewable): Non-conventional energy sources are the one which are called as renewable resources too because they can be renewed. Examples of renewable resources are solar energy, bio-energy, wind energy and tidal energy. Biomass: Biomass is a renewable resource which can be renewed easily and is formed from organic matter. It occurs in the form of living or recently living plants and waste and is contained inside the plants and animals. Conversion of biomass into other energy is done by combustion, gasification, pyrolysis, bio-digestion and fermentation. Disadvantages: They are renewable but there is risk of deforestation. It requires a lot of water. Biomass is inefficient as compared to other fossil fuels. It is not really clean or safe. Advantages: Biomass is a renewable resource. It is widely available and less expensive as compared to other fossil fuels. It can be used to produce or make different products like
Kinetic energy is moving energy and can be found through the equation KE=(½)mv². Energy is measured in the units of Joules or j. Potential energy is another form of energy that is energy that has the ability or potential to make matter move once it is released. Energy cannot be destroyed or created, rather is is transformed into other types of energy (for example kinetic to electrical). Mass is also another type of energy (mass energy) and it is just the mass of an object or the energy of being. Chemical changes cause atoms to be altered or changed while physical changes do not affect the chemical state of an object.
Unit 5 Anatomy and Physiology for Health and Social Care P4 Explain the physiology of two named body systems in relation to energy metabolism in the body The two body systems selected in relation to energy metabolism in the body are the digestive system and cardiovascular system. The digestive system breaks down foods and the cardiovascular system enables absorption and usage of the food. The term energy metabolism in the body relates to chemical reactions that that maintain cells and organisms. It is divided into two categories: catabolism is the breakdown of molecules to obtain energy and anabolism the synthesis of all compounds needed by the cells.
This high production of biomass energy and reusing waste has more potential than just West Texas. Texas contains several farms, waste-water plants, and agricultural land to utilize for biomass energy
Looking at the difference of ethanol fuel and gasoline, the benefits of ethanol fuel by far outweigh gasoline. With ethanol fuel being made from biomass the amount of greenhouse gas emissions is greatly reduced from those of gasoline emissions. This is allowed to happen because when ethanol fuel is burned, it is burned in almost complete combustion making the emissions much more clear and less harmful to the environment. With a reduction of greenhouse gas emissions the benefits to the environment are huge. Our economy would be allowed to spend less money on environmental factors and more for the people.
It leads through the whole process of the products and how it has changed throughout the years. This book was written by David Courtwright and
Due to these issues, renewable resources should become our primary source of energy. First, there are many issues with the energies sources we use now, but one of the major ones is that nonrenewable resources cannot replenish fast enough to replace what is being consumed. Energies made from fossils are the most common types of nonrenewable resource. Specifically, the three main types of fossil fuels are coal, natural gas, and oil.
It is commonly used in organic chemistry laboratories suction filtration or vacuum filtration. The solution can be supersaturated, unsaturated or saturated. Vacuum filtrations is used to assemble recrystallized
For example, as a roller coaster goes downhill it builds kinetic energy. Potential energy is energy of an object that does not move at all. Think of a book on top of a table, it doesn’t move at all. Another example is a roller coaster on the top part of the hill before it goes down. The potential energy is converted into kinetic energy once it falls downhill.
It is commonly known throughout human history that the energy used is burned from coal which creates biomass. During the Industrial Revolution, coal was an essential need to everyone, hence the discovery of oil as a substitute. Yet, the mass formation from the unearthing of oil causes more damage than benefits for the planet. Humanity had never seen a more compatible source in which came a higher demand for oil. As the public has urged to generate more oil, scientists theorized that fossil fuels will eventually run out, making way for a renewable energy route in the future (Mason).
wind energy and solar energy are both renewable types of energy they create no pollution and are fully sustainable as they are both powered by natural sources and if there is no wind one day the solar panels can generate energy and if it 's cloudy another day the windmills can generate energy also the energy created during the summer can be sold to the grid for extra capital that can be used for field trips, renovations, etc. Geothermal heating systems are rated the most efficient and eco-friendly heating systems. The system works using buried coils that contain a liquid, typically a mix of water and antifreeze. The liquid is warmed to the same temperature as the earth and then runs through to the home where a compressor extracts the heat but not only that geothermal heating requires no fossil fuels so it is very eco-friendly LED lighting is an efficient and eco friendly lighting alternative because they waste much less energy in converting to light compare to incandescent lights which waste 90% of the energy to convert to heat not only that LED lights last up to 15-25 times longer that traditional light bulbs this makes LED a much better source of lights than others because it wastes less energy and it is more efficient at doing its job this is so much better for the environment because it uses less energy that other lighting sources
Almost none of the fuel sources that we could use provide Co2 or other pollutants. Economic values could also come from renewable energy. Most of the Energy projects are located away from big cities. These benefits could bring local service as well as tourism. Although the pros are very big there are some cons.
Another major challenge in the exploitation of non-renewable resources is that they have negative environmental, social and economic impacts that have far reaching implications ranging from climate change to loss of biodiversity. 2.2 NON-RENEWABLE ENERGY RESOURCES Non-renewable energy resources can
Renewable energy is generally defined as energy that comes from resources which are naturally replenished on a human timescale such as sunlight, wind, rain, tides, waves, and geothermal heat. It is the energy which is abundant in nature. The sun is the ultimate source of energy. Almost all the energy that we use eventually comes from the Sun. The exception is the heat of radioactivity deep inside the Earth, which is ultimately responsible for processes taking place inside the Earth.
Building Strong Relationship with Positive Energy Energy Energy is defined as the capacity for work or the force that helps us do things with vitality and intensity. This energy would be further classified into Negative or Positive; Negative Positive Negative, stressful work environments results in - Physical fatigue - Decreased optimism - Lower morale Positive, work climate makes workers feel - Uplifted - Encouraged - Empowered
For example, rice cooker. It is used in most consumers’ daily
