Petr Holub: The USA has set out in the right direction to reduce emissions through energy-efficient buildings

Its job creation plan includes more than $ 200 billion invested in the construction and renovation of buildings, with an emphasis on energy savings and the resilience of human homes to climate change such as extreme temperatures and droughts.

The US administration has thus correctly estimated investments in energy-efficient buildings as a way of reducing emissions that goes hand in hand with economic growth. Energy efficiency can save more than 40% of the world's total emissions from the next 20 years, according to calculations by the International Energy Agency (IEA), which has long called energy efficiency the "first fuel".

The energy that does not need to be produced is the most ecological. According to the IEA, the basis of global emission reductions is precisely high-quality energy-efficient renovations of buildings, which, in addition to environmental benefits, increase energy self-sufficiency and significantly increase public spending. For example, in terms of job creation, they are the most advantageous of all possible energy measures, says the IEA.

The Czechia, together with other European countries, is currently looking for ways to reduce emissions by at least 55% by 2030 compared to 1990. Europe is likely to agree on a breakdown of the target according to the possibilities of individual states. However, even if the Czechia decides to fill as much as 55%, energy savings in buildings will play a key role. Already today, Czech emissions are 35% lower than in the early 1990s. The buildings are able to fill at least three quarters of the remaining twenty percentage points. By 2050, they can save about five times more emissions than the construction of a new Dukovany unit.
