Pär Holmgren: Sluta klaga – köp ditt eget kraftverk Det är många i Sverige som i dag betalar onödigt mycket för sin el. När elpriserna går upp klagas det över höga elpriser, men i stället för att klaga kan många mycket enkelt se till att kostnaden för elen blir lägre. För drygt tio år sedan köpte jag och min fru andelar i vindkraft. Vi betalade då totalt 24 000 kronor för fem andelar som sedan dess har gett oss 5000 kWh per år till självkostnadspris.

Ecosystem services Humankind benefits in a multitude of ways from ecosystems. Collectively, these benefits are known as ecosystem services. Ecosystem services are regularly involved in the provisioning of clean drinking water and the decomposition of wastes. While scientists and environmentalists have discussed ecosystem services implicitly for decades, the ecosystem services concept itself was popularized by the Millennium Ecosystem Assessment (MA) in the early 2000s.[1] This grouped ecosystem services into four broad categories: provisioning, such as the production of food and water; regulating, such as the control of climate and disease; supporting, such as nutrient cycles and crop pollination; and cultural, such as spiritual and recreational benefits.
