On the sidelines of the Kigali Cooling Efficiency Program annual meetings, an awards ceremony was held to recognise those champions clean and efficient cooling. Rwanda was recognised for being the first country in the world to develop a National Cooling Strategy and for its efforts to develop minimum energy performance standards for cooling appliances.

History:
The railway comes to Finland:
When visiting Finland in 1856, Grand Duke of Finland Alexander II of Russia proposed an improvement program for the Finnish economy. He thought it was important to connect the inland country to the marine harbours through canals and railways. So planning of Finland's first railway from Helsinki to Hämeenlinna was started.
Location of the railway and the station:
A 1853 railway project proposed the northern edge of the Hietalahdentori square as the location of the Helsinki railway station. A later proposal in 1857 was at the vicinity of the Turku barracks, and a third option was the environment of the Kluuvi well. Investigation of the new railway line in summer and autumn showed how difficult it would be to build a railway into the city of Helsinki, which was located at the point of a peninsula. The research resulted in four different options of the railway line. These options differed greatly in cost. The original plan included 40,800 Russian roubles for the main station of the railway, but the most expensive option was estimated at 162,000 roubles.
The cheapest option would have had the railway to make a curve after Pasila and go around the Töölönlahti bay. The second option would have had the railway go directly west from Pasila past the Töölö sugar factory. The third option would have passed Pasila entirely and continued around Töölönlahti. All these options would have located the station to the south of the Turku barracks. In the fourth option, the track would go from Pasila straight across Töölönlahti and the Kaisaniemi Park to Kluuvi, with the station located immediately after the Kluuvi well. This option was the most expensive, costing about 107,970 roubles. Of the four options, it required the most of blasting the bedrock and filling the Kluuvinlahti bay.
The three first options required dismantling villas and other buildings from the shore of the Töölönlahti bay and building railway tracks on beautiful and farmed land from the environment of the city. In addition, the costs of the compulsory purchase of the land would have been significantly greater than in the fourth option. Another concern was that a steep curve directly after the railway station would cause more wear on both the tracks and the train wheels. This would result in danger of the train tilting, causing a decrease of the efficiency of the engine. The option for the straight railway line had the benefit of an unobstructed view from the station to the traffic on the tracks. The fourth option received the most support, and it was accepted on 26 November 1857.
The choice was perhaps also influenced by Knut Stjernvall serving as the technical director of the railway company at the time, whose stepfather Carl Johan Walleen [fi] owned Villa Hakasalmi on the western shore of the Töölönlahti bay. The three other options would have required dismantling the villa.
Because of the decision, citizens of Helsinki started worrying about the fate of the Kaisaniemi Park located next to the Kluuvi well. It was clear that the railway would override part of the park area. Per the request of the citizens, the railway line was moved slightly to the east in 1859, in order to preserve the two large and beautiful hills in the park.
Filling the Kluuvinlahti bay:
The area where the station was planned to be built was originally seabed. In the 19th century the area was a muddy and stinky water area used as a dump and a public outhouse. Filling the Kluuvinlahti bay originally started already in the 1830s, but the filling really came into action when the railway was being built
The bay was confined at Hakasalmi, ditches were dug into the Kluuvi swamp, and a stone-walled assembly pool was built behind the dam, from where the water was pumped into Töölönlahti by wind power. Many horse cart loads of sand were dumped into the area during the decades.
According to the plans in the 1830s, the area to the north of Kaivokatu and to the west of Mikonkatu was to be divided into two blocks, which were named Hyeena ("hyaena") and Hilleri ("polecat"), separated by the street Hakasalmenkatu, now known as Keskuskatu. The decision to build the railway decided the fate of the Hyeena and Hilleri blocks. Knut Stjernvall made the final railway plan in 1859. He proposed that a wide market square should be built on the place of the Hyeena block east to the railway yard. The few buildings left in the Hyeena block were dismantled, and it was changed into what is now the Rautatientori square. Construction of the first railway station in Finland started at the edge of the Hilleri block.
The construction of the railway station had a great impact on the Helsinki cityscape. The railway was piled with large logs, and stones were laid on the edge of the bay. Aspen trees had to be cut down from the Kaisaniemi Park to make way for the railway, but the park was preserved whenever it was possible to do so. Rock blasted off the Linnunlaulu cliff was sunk into the Töölönlahti bay beneath the railway tracks being constructed. The railway terracing over the Töölönlahti bay was completed in March 1861. For water traffic, two underpass bridges were built vaulted from stone. The larger underpass bridge had a size of 7 cubits (10 ft 6 in/3.20 m) and the smaller one had a size of 3 cubits (4 ft 6 in/1.37 m). The rails for the railway tracks were bought from the United Kingdom, and they arrived by steamship into the South Harbour in November 1857.

I finally took the advice of a lot of experienced riders and put toe cages on my pedals. You can pedal much more efficiently if you spin faster in a lower gear. (I should note that my bike ride is hella hilly in places. When I lived in Copenhagen I never had this problem.) When your goal is to arrive with as little sweat as possible, this is key. It's hard to spin smoothly with your feet in the right position, though, without some sort of cage or clip. Clips require special shoes. Cages like these, made from hard plastic and without the entangling straps on the sides, are just about perfect for me.
The Northwest Energy Efficiency Alliance's 2023 Efficiency Exchange (EFX) Conference took place at the Oregon Convention Center in Portland. On May 2-3, 2023, regional and national attendees from public and private utilities, consulting and research firms, and government and non-profit organizations came together to learn and connect to help the region more effectively achieve its energy efficiency goals.
