Western Macedonia has grown in the last century mainly due to its coal deposits. Lignite mines and power plants were important local employers. The regional capital, Kozani, is still the leading energy producing area of Greece .

As one of her final acts as Prime Minister, Theresa May , announced that she will be signing into law a pledge to reach net zero carbon emissions by 2050 . This would make Britain the first member of the G7 to make such a commitment official.

Whether you are arriving to or departing from Helsinki Airport, the first thing you notice is the glass around you and the characteristic Finnish design.

If energy-saving measures came knocking at the door, wouldn't it be reassuring to have someone on hand to help you navigate the benefits and inconvenience, someone to help dispel your doubts? This is what is happening in Zaragoza, Spain, where social workers are helping the dwellers of a block of council flats.

It is one of the most famous museums in the world, with more than one million visitors every year. If you happen to visit Bilbao, Spain, you can’t miss the Guggenheim .

Playing games could be a solution to saving energy. Using energy more efficiently is, of course, a crucial part of fighting climate change, since oil and fossil fuels continue to be the most important energy source in the world, including Europe .

When you hear Uffizi, Accademia and David what do you think about? Florence, for sure. For its old history, breathtaking painting, sculpture, and architecture.

Today´s liberalised markets are focused on short-term return on capital, but energy infrastructure planning should be driven by the objective of climate protection.

Door locks that open with fingerprints, networked security cameras, smart light bulbs, smart washing machines: technology is transforming our homes, turning the tech dreams of yesterday into the reality of today.

There is no such thing as a perfect energy efficient process. The second law of thermodynamics states that all energy generating processes produce heat as a by-product.

Some modern systems are now using sustainable heating sources, like waste heat from power plants . Could this approach contribute to fight climate change? We report from Western Turkey where the city of Soma is taking a new approach to increase energy efficiency in a residential area.

Building with wood, straw, and hemp. Biobased materials are seeing ever more use in the construction sector, which needs to become more sustainable as it is one of the major sources of soil, air and water pollution.

Thirty-one apartment buildings comprising 140,000 m 2 of floor space: Europe’s most ambitious energy-saving renovation project is transforming Torrelago, a residential district of Valladolid in central Spain.

  In the suburbs of Valladolid, a city in central Spain, a district is at the forefront of Europe's energy transition.

Some 15.4 % of the EU population reported that they live in dwellings with a leaking roof, damp walls, floors or foundations, rot in the window frames or the floor. And some 8.7 % are unable to keep their home warm enough.

Blockchain technology enables secure trading without a centralised intermediary like an exchange. This makes it attractive not only for cryptocurrency , where it was applied first to bypass banks, but also for large decentralised energy systems with a high share of renewable energy .

At the end of June 2018 the Baltic countries and Poland came to a political agreement for synchronising the Baltic States' electricity grid with the continental European network by 2025.

Wind and solar energy is not constant and therefore a renewables-based society requires smart grids to transport this power from areas where electricity generation is currently high to those where it is low in order to meet demand.

In addition to solar, wind power is growing as a source of alternative energy, and is expected to occupy a major portion of the market by mid-century.

For most of us, any concerns about computing speed or data storage are usually to make it go faster while storing more. We hardly ever think about the enormous amounts of energy already required to power Internet servers or charge the increasing number of devices we own.
