Energy & Climate Glossary DTEK's Energy Expertise DTEK in Ukraine: energy, light and heat for society.

B

Biofuels are fuels that are created from biomass in a short period – contrary to the long-term formation of fossil fuels. Fuels produced from plants, and agricultural, domestic, and industrial waste are essential in the renewable energy transition and sustainability efforts.

C

Carbon Offsetting

Everything we do releases CO2 into the atmosphere. Working, travelling, eating, and using the internet result in a certain footprint. Carbon footprint offsetting is what inverts this effect. It helps remove CO2 from the atmosphere.

D

Decarbonisation

Decarbonisation is changing the usage of fossil fuels and non-renewables to carbon-free and renewable power. The process is aimed at processes that use coal, oil, and natural gas, and promote minimising greenhouse emissions in major energy sectors.

E

Emissions Trading

Emissions trading, also known as cap and trade (CAT) or emissions trading scheme (ETS), is a way to reduce pollution of our planet. The concept can often be found in the definition of carbon offsetting, as it provides economic incentives for decreasing CO₂.

Energy efficiency

The definition of energy efficiency encompasses several ideas, such as optimising how we use electricity and fuel, smart management, and trying to achieve as much performance as possible by utilising as little power as we can.

Energy transition

An energy transition is a total change of the power supply and consumption. The term went through several changes according to the history of the global power sector. The transformation we see right now is all about minimising the effect of climate change.

Energy-as-a-Service (EaaS)

When searching for "What is EaaS?", many consumers get confused about its definition. Indeed, the system is new and is just emerging among electricity providers. It can help boost the renewable energy transition, generate revenue, and enhance resilience amid blackouts.

H

Hydrogen fuel

Hydrogen fuel is an environmentally friendly solution that only leaves clean water after producing electricity. It can also be produced in a broad variety of ways, including natural gas, nuclear power, biomass, solar, and wind.

M

Microgrid

The definition of microgrid varies from source to source. For instance, the United States Department of Energy Microgrid Exchange Group states that it is a group of interconnected loads and distributed energy resources.

R

Renewable energy

Renewable energy comes from unlimited sources. We can never run out of airflow and sunlight, for instance, as the environment always replenishes them.

W

Waste-to-energy technology

Waste-to-energy technology (WtE) is a process of utilising different types of waste to receive energy. Typically, electricity or heat are the result. WtE is a huge part of decarbonisation and sustainable energy production, as it helps both minimise the rubbish in landfills and use an alternative power source.

Wind turbine

Wind is one of the most abundant natural resources on the planet. While the power of airflow varies depending on the area, it is already effectively captured by wind energy turbines and converted into electricity.
