The nucleus of an atom contains protons and neutrons held together by nuclear binding energy. This energy prevents particles from leaving and repelling each other. The mass of the nucleus comes from the particles’ isolated mass and the binding energy. The nucleus of an atom is its central nucleus, which consists of one or more […]
Solar energy from the sun can be converted into other forms of energy. Most renewable energy sources come from the sun, except for geothermal and tidal energy. Solar energy arrives as light waves, with some being reflected back into space. Humans can use solar energy indirectly or directly through photovoltaics. The technology for harnessing solar […]
Thermal energy storage uses a thermal reservoir to store energy for later use. Water’s ability to store large amounts of heat or cold is used, with air conditioning systems being a common application. Ocean thermal energy conversion also utilizes natural thermal energy storage in the ocean. Thermal energy storage is a means of storing energy […]
Renewable energy turbines use wind or water to generate electricity through rotating blades. Wind farms contain multiple turbines, while water turbines can float. The turbines contain motors, gears, and controllers that drive a generator to produce electricity. Wind turbines can be vertical or horizontal and come in various designs. Both wind and water turbines are […]
The laws of energy are defined by the three laws of thermodynamics, Einstein’s theories of relativity, and Newton’s laws of motion. Energy cannot be created or destroyed, but can be transformed into other forms. Einstein’s formula E=MC2 showed that matter and energy are interchangeable. The second law of thermodynamics explains the principle of entropy, where […]
Biogas energy is produced from decomposing organic material and can be used to power vehicles, generate heat and electricity. It is a cheap and renewable energy source that can be implemented in low-income communities. Biogas digesters are available commercially or can be built. It is part of a larger picture to reduce dependence on fossil […]
Becoming an energy auditor requires post-secondary education, related work experience, applying for a job, and completing the interview process. Energy auditors verify energy creation, transportation, and management, identifying areas of waste. This role requires attention to detail, independence, and a commitment to efficient resource management. An engineering degree is common, and related experience includes power […]
Ocean thermal energy conversion (OTEC) uses the temperature difference of the ocean at various depths to create a heat engine, converting thermal energy into mechanical output. The first energy conversion ocean thermal plant was built in Cuba in 1930. There are three types of OTEC systems: closed, open, and hybrid. Closed-loop systems use a low […]
Bond energy is the energy needed to break chemical bonds between atoms, expressed as kilojoules per mole of bonds. The type of bond and atoms involved affect bond energy. Chemists use bond energy to predict chemical reactions and calculate energy release or input. Bond energy is a term used in chemistry to describe the amount […]
Potential energy equations explain how energy is stored in various systems, such as elastic potential energy in springs and gravitational potential energy on Earth. Chemical reactions and nuclear fission also involve potential energy. Work done on a system equals the potential energy lost. Several equations used in science come from a potential energy equation. A […]
Solar energy technology has led to a growing range of gadgets and tools, from outdoor lighting to solar-powered pool heating discs and emergency power kits. Solar panels can replace traditional electrical systems, providing clean, renewable energy and reducing utility bills. The potential for solar energy is vast, with the possibility of entire cities running on […]

Educational requirements vary, but a post-secondary certificate or associate degree is sufficient. As an energy analyst, you will advise customers on energy savings and perform energy audits. To become an energy analyst, you […]
Incident energy is energy that is created from an accident and transferred to other objects. It can be thermal or kinetic and is absorbed by objects in its path. Incident energy is important for solar panel design and worker safety procedures. In technical terms, incident energy is energy that falls or hits something and then […]
Energy analysts work in policy development, efficiency improvement, and business analysis for investors. Qualifications vary, but may include science or business degrees and industry experience. They can work for government agencies, non-profits, and private companies. They assess energy usage and provide suggestions for improvement, advise investors, and write opinion columns. Advanced training in environmentally friendly […]
Education in solar energy is essential for technicians, architects, and engineers. Solar energy is a significant source of renewable energy, used for heating buildings and generating electricity. Colleges and technical schools offer solar energy courses, and universities have specialized programs. Job opportunities include solar energy technician, engineer, and project manager, requiring different levels of education […]
Renewable tidal energy is generated by ocean tides using underwater turbines or tidal generators. It is a reliable and effective form of alternative energy, but there are few locations with sufficient tidal range for large-scale power generation. Tidal barrages and weirs may also harm the environment. Renewable tidal energy, also known simply as tidal energy […]
Renewable green energy comes from infinite sources and reduces air pollution. Examples include solar, wind, and hydroelectric energy. Non-renewable energy sources like coal and oil are unsustainable.
