Sources of energy that are naturally replenished and don't deplete natural resources. Examples include solar, wind, hydro, and geothermal.

Energy harnessed from the sun, usually through solar panels to generate electricity.

Energy obtained from the movement of air, used to generate electricity by wind turbines.

Energy from moving water, harnessed in hydroelectric power plants to generate electricity.

Energy from Earth's internal heat, used to generate electricity with geothermal power stations

Systems like batteries and pumped hydro to reliably use renewable energy when needed.

Technologies for reducing greenhouse gas emissions from fossil fuels and industries.

Shifting from traditional energy sources to renewable energy sources.

Devices that convert sunlight into electricity.

Solar technologies that directly convert sunlight into electricity using solar panels.

Solar technology focusing sunlight to heat a fluid, generating electricity.

Machines that convert wind's kinetic energy into rotational energy to generate electricity.

Most common type of wind turbines with blades rotating around a horizontal axis.

Less common type of wind turbines with blades rotating around a vertical axis.

The cost of wind energy has significantly decreased in recent years.

Wind speed and direction fluctuate, making wind energy unreliable.

Energy storage stabilizes the grid and ensures a reliable power supply, especially during peak demand.

Different storage methods exist, including batteries, pumped hydro, compressed air, and thermal energy storage.

Common storage method that converts chemical energy to electrical energy (batteries, fuel cells, supercapacitors).

Stores energy as heat or cold, commonly used in solar and HVAC systems.

Stores energy as kinetic or potential energy (flywheels, compressed air, pumped hydro).

Stores energy in chemical bonds (hydrogen, methanol).

A technology that captures carbon dioxide directly from the atmosphere.

A carbon capture technology that captures CO2 after combustion in power plants.

A carbon capture technology that captures CO2 before combustion in power plants.

Batteries convert chemical energy stored within them into electrical energy that can power devices.

A carbon capture technology that burns fuel in a high-oxygen environment, making CO2 easier to capture.

Batteries are portable, rechargeable, have a long lifespan, and can store energy for later use.

Batteries are expensive to manufacture, have limited storage capacity, and require proper disposal to avoid environmental damage.

CCS technology can significantly reduce greenhouse gas emissions, mitigate climate change, improve air quality, and reduce the environmental impact of fossil fuel use.

CCS technology can be expensive, energy-intensive, and may have technical limitations.

Pumped hydro storage uses excess electricity to pump water uphill, storing it in a higher reservoir. When needed, the water flows downhill through turbines, generating electricity.

CCS technology involves capturing carbon dioxide emissions from industrial sources, transporting it, and storing it underground in geological formations.

Pumped hydro storage is cost-effective and environmentally friendly for storing large amounts of energy, helping to balance intermittent renewable energy sources like wind and solar.

Pumped hydro storage requires extensive water and land, can impact local ecosystems, and depends on suitable locations.

They are portable, rechargeable, have a long lifespan, and can store energy for later use, making them convenient for devices and applications.

It can store excess energy generated during periods of high wind or sunlight and release it when needed, helping to ensure a consistent supply of electricity.

The network of processes and infrastructure involved in producing, transporting, and delivering energy from its source to consumers.

A complex network of interconnected power lines and substations that deliver electricity to consumers.

Modern, digitalized electric grids that integrate advanced technologies for efficient and reliable energy management.

A fusion reaction that releases enormous energy by combining light atomic nuclei, like hydrogen, into heavier ones.
