What Is The Source Of Energy For A Solar Panel – Various sources of energy can be used to power human activities, and often this energy must be transferred from source to destination. Energy Literacy Principle 4 Scroll down to: Teaching these ideas Find activities

Learning about energy sources is supported by 7 key concepts: 4.1 Man transfers and transforms energy from the environment into forms useful for human endeavours. Primary sources of energy in the environment include fuels such as coal, oil, natural gas, uranium and biomass. All primary source fuels except biomass are non-renewable. Primary sources also include renewable sources such as sunlight, wind, moving water and geothermal energy. There are 6 more basic concepts. View them all… Hide4.2 Human use of energy is subject to limits and restrictions. Industry, transport, urban development, agriculture and most other human activities are closely linked to the amount and type of energy available. The availability of energy resources is limited by the distribution of natural resources, availability of available technologies, socio-economic policies and socio-economic status. 4.3 Fossils and biofuels are organic matter that contains energy captured by sunlight. The energy in fossil fuels like oil, natural gas, and coal comes from energy that was captured by sunlight long ago by producers like plants, algae, and cyanobacteria. The energy in biofuels such as food, wood, and ethanol comes from energy captured by producers from sunlight very recently. The energy stored in these fuels is released in chemical reactions such as combustion and respiration, which also release carbon dioxide into the atmosphere. 4.4 People transfer energy from place to place. Fuels are often not used at the source but are transported, sometimes over long distances. Fuels are mainly transported by pipelines, trucks, ships and trains. Electrical energy can be generated from a variety of energy sources and can be converted into almost any other form of energy. Electric circuits are used to distribute power to remote locations. Electricity is not a primary energy source, but an energy carrier. 4.5 People generate electricity in different ways. When the magnet moves or the magnetic field changes relative to the coil of wire, electrons are induced to flow through the wire. Most human electricity production is done this way. Electrons can also be made to flow through direct interaction with light particles; this is the basis on which a solar cell works. Other methods of generating electricity include electrochemical, piezoelectric and thermoelectric. 4.6 Humans intentionally store energy for later use in several different ways. Examples include batteries, water storage, compressed air, hydrogen and thermal storage. Energy storage involves many technological, environmental and social issues. 4.7 Different sources of energy and different ways of converting, transporting and storing energy have different advantages and disadvantages. A given energy system, from source to sink, will have its own level of energy efficiency, monetary cost and environmental risk. Each system will also have implications for national security, access and equity.

An energy transition is underway. The 2016 Paris climate agreement sent a clear signal that a global shift towards low-carbon energy is absolutely necessary. Countries endorsed the deal at the 2021 Glasgow climate conference, and despite political variability in US commitment to climate change, the clean energy transition continues unabated, often led by other nations and US states, cities and corporations.

The origin of our energy supply is an exciting and engaging topic for students and is a great way to learn about the different ways we get energy, as well as the impacts and social consequences of different types of energy. These concepts revolve around energy that is used for human purposes, including renewable and non-renewable energy sources, energy storage, electricity generation, and transportation of energy from place to place.

An essential starting point for this topic is the concept of renewable vs. non-renewable energy sources. Many students are already familiar with the idea that fossil fuels regenerate much more slowly than we use them and are therefore non-renewable. Renewable energy comes in many forms: hydro, solar, wind, geothermal and biofuels. Each of them offers a number of related themes and nuances. For example, solar energy can be produced on a single roof or in large solar farms. Solar power can also be generated in concentrating solar power plants, which use an array of mirrors to direct the sun’s energy into a central tower. This type of solar energy can provide power even at night. A detailed study of energy production can prevent too simplistic labeling of specific types of energy as good or bad.

It is also useful to deal with the practical and technological aspects of energy. The distribution of energy resources around the world is uneven, as some regions have sufficient energy resources while others do not. The areas where energy is used most intensively are not necessarily the same places where energy sources naturally exist. For example, rich oil and gas deposits are located in coastal marine environments and wind farms are located in rural environments. In both cases, this energy is transported to the place where the energy is consumed. In addition, final energy use varies by geographic location, season, and time of day. Therefore, energy must be transported, stored and converted from one form to another so that it is available when and where it is needed.

Today’s students are witnessing a renaissance in energy technology. After decades of fossil fuel-dominated energy use, a wide range of innovative possibilities await exploration. The world’s transition away from carbon-intensive fuels is a highly topical topic that offers rich, relevant and multifaceted learning opportunities. Learning about energy sources can be approached from the perspective of engineering, public health, economics or international business – a multidisciplinary approach is ideal (these ideas are also covered in Energy Decisions).

Just as ecosystems depend on the supply of energy, human societies also depend on energy for infrastructure, transportation, food, and most other types of human activities. However, there are limits to how much energy is available to a given company. Even renewable forms of energy are dependent on geographic location and technological availability. Non-renewable energy resources are limited and have an impact on their extraction, transportation and consumption. Energy prices, energy equity and energy security are factors that determine how easily energy is available to different parts of society. Some companies have a surplus of energy, while others struggle to meet their basic needs. As students become familiar with these concepts, they can begin to see how humans depend on the use of energy, but are also limited by the practicalities of using energy.

Most students already understand that energy can come from many sources. However, they may have misconceptions about where their energy comes from or how much energy comes from different sources. For example, students may be surprised to learn that only a small portion of the US energy supply comes from wind turbines and other renewable sources (12% in 2021), while 79% comes from fossil fuels. Nuclear power provides 8% of the US energy supply (Energy Information Administration, 2021). Despite the popularity and importance of renewable energy technologies, it is important to understand that fossil fuels still form a significant part of our energy portfolio, especially for non-electrical uses such as heavy industry, transport and home heating. However, with the passage of the Inflation Reduction Act (IRA) of 2022, renewable energy generation is projected to surpass non-renewable generation in the coming decades (Outlook 2023 according to the Energy Information Administration).

This illustrates the extraordinary challenges we face in moving beyond fossil energy. The transition away from fossil fuels brings a new set of issues, such as energy storage, battery technology, and power supply that is linked from many intermittent sources rather than a few steady-state power plants.

Today’s students are likely to be excited about renewable energy, which is a great way to engage them. But they must learn about the challenges and realities of overhauling the power system. Consider, for example, the large-scale renewable energy installations that will be required to replace the 79% of energy supplies that come from fossil fuels, and the logistics of locating wind turbines, solar farms, or other new energy infrastructure. Numbers are important. The quantitative treatment of these entities clearly shows that we have a long way to go to ensure a reliable, safe and clean energy supply.
