Energy (General)
This is the ability to do work or cause change.
Energy
This process occurs when the nucleus of a heavy atom splits into smaller nuclei, releasing energy and neutrons.
Nuclear fission
This form of renewable energy utilizes the temperature difference between warm surface water and cold deep water in the ocean to generate electricity.
Ocean thermal energy conversion (OTEC)
This renewable energy source is generated by capturing sunlight using solar panels, which convert sunlight into electricity through the photovoltaic effect.
Solar energy
This renewable energy source is generated by harnessing the heat from beneath the Earth's surface, often using steam or hot water to drive turbines and generate electricity.
Geothermal energy
This type of energy comes from naturally replenishing sources like the sun, wind, and water.
Renewable energy
This reaction powers the sun by combining light atomic nuclei to form a heavier nucleus, releasing vast amounts of energy.
Nuclear fusion
The disadvantages of hydro energy include disrupting aquatic ecosystems, displacing communities due to dams, sedimentation affecting water quality, and inconsistent power generation in areas with fluctuating water levels. .
Disadvantages of Hydro Energy
The installation of these systems can be costly, but the long-term savings on electricity bills can make it cost-effective over time.
The challenges of solar energy
These natural formations, found beneath the Earth's crust, release heat that can be used for generating electricity or heating buildings.

Chemical Reaction for Nuclear Fisson
Hydro energy is a renewable energy source that generates electricity by harnessing the power of flowing water, typically through dams or turbines. The movement of water drives turbines, converting kinetic energy into electricity. While it’s a clean energy source, hydro energy can impact aquatic ecosystems and fish migration. Run-of-the-river hydroelectric plants generate power without large dams, using natural water flow and drops.
Hydro Energy
Solar power is considered a renewable resource because the sun provides a continuous supply of energy, making it sustainable in the long term.
Renewable solar energy
Geothermal energy is considered sustainable because the heat from the Earth is continually replenished, but it can be location-dependent, as it is most effective in areas with significant volcanic activity.
Benefits and limitations of geothermal energy
This term refers to using less energy to perform the same task, often through improved technology or design.
Energy efficiency
producing a large amount of energy from a small amount of fuel, emitting low greenhouse gases, and providing reliable, continuous power. However, it = includes the risk of nuclear accidents (like Chernobyl and Fukushima), the creation of hazardous radioactive waste that remains dangerous for thousands of years, high initial costs for building nuclear plants, and the finite supply of uranium. Additionally, there are security concerns about nuclear proliferation, where nuclear technology could be used to create weapons-grade materials.
Advantages and Disadvantages for Nuclear Energy
Tidal energy is a form of renewable energy that generates electricity by harnessing the rise and fall of ocean tides, often using underwater turbines or tidal barrages. This energy source is considered clean, but it can have environmental impacts, such as disrupting marine habitats. One advantage of tidal energy is its predictability, as it relies on the gravitational pull of the moon and sun, making it more reliable than wind or solar energy.
Tidal Energy
These devices are used to convert sunlight into electricity by using semiconductor materials that absorb photons and release electrons.
Solar panels (photovoltaic cells)
Geothermal power plants are typically low in emissions, making them a clean energy source, but they require high upfront costs for infrastructure and drilling.
Challenges of geothermal energy
This type of energy comes from natural replenishment sources, like solar power in Jamaica, wind energy in Barbados and the Dominican Republic, and hydropower in Saint Vincent and the Grenadines. And these types of energy in the also Caribbean include natural gas in Trinidad and Tobago and petroleum, which is imported for transportation and electricity.

This process involves several key steps: First, a heavy atom, like uranium-235, is bombarded with a neutron. This causes the atom's nucleus to split, releasing a large amount of energy in the form of heat. The heat is used to produce steam from water. The steam then drives turbines, which are connected to generators that produce electricity. This chain reaction continues as the released neutrons go on to split more atoms, maintaining the process.
The process of producing nuclear energy
Wave energy is a form of renewable energy that harnesses the movement of ocean waves to generate electricity. Waves are formed by the wind blowing across the surface of the ocean, transferring energy to the water. This energy is captured using devices like wave energy converters (WECs) that float on the water's surface and move with the waves. Wave energy is environmentally friendly, producing no emissions, but it can impact marine ecosystems. However, it faces challenges such as high initial costs and the need for infrastructure in harsh ocean environments.
Wave energy and its benefits and challenges
Solar energy is considered a clean and renewable energy source because it generates electricity without emitting harmful pollutants or greenhouse gases. Unlike fossil fuels, it does not contribute to air pollution or climate change. However, the efficiency of solar energy can be impacted by factors like weather conditions (e.g., cloudy days or storms) and geographic location. Areas with more sunlight, such as deserts or tropical regions, tend to have higher solar energy potential, while regions with less consistent sunlight may see lower efficiency. Additionally, seasonal changes, such as shorter days in winter, can affect the amount of solar energy generated.
Benefits and limitations of solar energy
Geothermal reservoirs are underground formations of hot rock, steam, or hot water that store the Earth's natural heat. These reservoirs are typically located in areas with high volcanic or tectonic activity, where the Earth's crust is thinner, allowing heat to escape. In geothermal power plants, wells are drilled into these reservoirs to access the steam or hot water. The steam is then used to drive turbines connected to electricity generators. There are two main types of geothermal reservoirs: dry steam reservoirs (which release steam directly) and wet steam or hot water reservoirs (which contain both steam and hot water). The temperature and depth of the reservoir determine how much energy can be extracted.
