developing areas. Energy self-sufficiency has been defined as total primary energy production divided by total primary energy supply. Energy trade includes all commodities in Chapter 27 of the Harmonised System (HS). Capacity utilisation is calculated as annual generation divided by year-end capacity x 8,760h/year. Avoided
Cuba: Many of us want an overview of how much energy our country consumes, where it comes from, and if we''re making progress on decarbonizing our energy mix. This page provides the data for your chosen country across all of the key metrics on this topic.
Cuba''s INDC commits to 19 bioelectric power plants fueled with wood and/or sugar cane residue (755MW), 13 wind farms (633 MW), solar photovoltaics (700MW), and 74 small hydroelectric plants for a total of 2,144 MW of renewable energy by 2030. Cuba must speed up their energy transition in order to meet their renewables goal while also generating
Residential energy use by source. In most countries, heating and cooling make up the largest share of energy use in homes. While air conditioners, appliances and lights generally run on electricity, combustible fuels such as natural gas, oil, coal and biomass are still widely used for heating and cooking.
To get an accurate picture of energy efficiency in a country, it is important to first look at how and where energy is being used. Total final consumption (TFC) is the energy consumed by end users such as individuals and businesses to heat and cool buildings, to run lights, devices, and appliances, and to power vehicles, machines and factories.
One way of looking at the overall energy efficiency of a country is to measure the total energy supply per unit of economic output (here adjusted for purchasing power parity). This reflects not only energy efficiency but also the structure of the economy, with services-oriented economies generally having a lower energy intensity than those based on heavy industry.
In most countries, heating and cooling make up the largest share of energy use in homes. While air conditioners, appliances and lights generally run on electricity, combustible fuels such as natural gas, oil, coal and biomass are still widely used for heating and cooking. Electrifying these end uses, for example by replacing fossil fuel boilers with efficient electric heat pumps, will be important for reducing CO2 emissions.
Residential energy intensity is largly driven by space heating, and to a lesser extent appliances. To allow cross-country comparisons, it is measured by floor area and temperature-corrected.
In most countries, transport energy use is dominated by oil used to fuel passenger cars, trucks and airplanes. Electrification of the transport sector, for example through the widespread rollout of EVs, is an important strategy for reducing CO2 emissions.
Passenger transport intensity is measured by the average amount of energy used to move one passenger over a distance of one kilometre. Intensity levels vary across countries depending on how people get around in that country – such as the modes of tranport used (e.g. driving, flying, rail), the types of vehicles used, and the average number of passengers per vehicle.
Industrial energy sources can vary considerably between countries depending on the structure of their economies. Many industrial processes, including steelmaking, cement and chemicals, still require fossil fuels for high-temperature heat or as feedstocks.
A country''s manufacturing energy intensity largely depends on the makeup of a country''s manufacturing sector: certain industries, such as basic metals and pulp and paper, are particularly energy intensive relative to their economic contribution.
The services sector tends to be much less energy intensive than industry, with the largest share of energy in most countries being used to heat and cool buildings. The shift from an economic structure based on heavy industry to one based on services has historically been a driver of falling energy intensity of advanced economies.
In the context of Cuba''s shift to more renewable energy sources for its future energy generation mix, energy storage becomes a critical component for the overall energy system of the country. After a general classification of the energy storage technologies, the two most promising energy storage methods, batteries and fuel cells, are discussed in more detail in this chapter. Fundamentals are presented to explain the differences between these technologies, and the most important battery and fuel cell systems are explained, including their advantage and disadvantages.
