![]() Additionally, a 2019 US Department of Energy (DOE) report found that by overcoming technical and financial barriers, generating electricity through geothermal methods could increase 26-fold by 2050, providing 8.5% of the US’ electricity, as well as direct heat. It is believed that Germany can go from 1.2 terawatt-hours of heat from geothermal today to 100 TWh by 2050.Ī recent report by the International Renewable Energy Agency (IRENA) predicted that the output of geothermal in Europe could increase eight-fold by 2050. A large geothermal plant is scheduled to go online this year to provide hot water to 80 000 houses. Munich, Germany, has a goal of switching the city entirely to district heating. ![]() ![]() ![]() The aquifer drills down nearly 2km to tap hot water, pumps it to the surface, distributes it around Paris and then re-injects it into the aquifer. In Paris, the Dogger Aquifer, first used for district heating in 1969, now supplies hot water for 250 000 homes and is expanding. Iceland, sitting on an active geological fault line, is a pioneer in the use of geothermal energy for heating and geothermal facilities currently generate 25% of the country’s total electricity production. China is also embracing geothermal energy, developing more geothermal district heating systems than any other country. The US produces 3.7 GW of geothermal electricity, enough to power more than 1 million homes, and is the world’s least producer. While geothermal is a blip on the alternative energy radar, 20 countries currently use geothermal energy. These two wells are in the same vicinity, but are not connected. Then, water is injected in one well, naturally heated by the geology, and pumped out a production well. As the solution travels through the pipe, it is heated by the high ground temperatures and then flows to the surface.įinally, there is the “open loop deep geothermal” system, where fluid is pumped under high pressure down a linked drill hole to break up hot rock its surface area- essentially a type of fracking. The hole is lined with pipe and then filled with fluid, acting as a natural radiator. However, as will be discussed later, a major hurdle for many homeowners is the cost, which can run into the tens of thousands of dollars per dwelling.Īnother kind of geothermal energy is a “deep closed loop” which typically consists of a single hole drilled deep into the ground, then laterally for a similar length through very hot geological formations, and then back up the surface. These pumps literally pump heat from the ground into a space, often homes. One is called “ ground source heat pump technology ” (GSHP) that extracts heat from the ground and depending on the climate, the source of this heat is either the sun or geothermal energy. Several types of geothermal are used today. There are three main types of geothermal energy plants: dry steam, which takes steam out of the ground and uses it to directly drive a turbine, flash plants, which use high-pressure hot water into cool, low-pressure water and binary plants, which pass hot water through a secondary liquid with a lower boiling point, which turns into vapour that then drives the turbine. Some units also have shields able to absorb the strength of an incoming attack partly or entirely.Geothermal is typically considered to be a local phenomenon as few places sit on underground rivers of steaming hot water, which is why it is not viewed as a particularly major player in the alternative energy landscape. Many units in WorldShift have power which the player can spend to perform special actions such as spells, healing, or stronger attacks. The game is centered on unique cooperative multiplayer gameplay. There is a three-tiered unit system, with outstanding leader units, strong officer units and then more common basic units. The players will gather items as they fight their opponents and as rewards for completing missions. In WorldShift, there are no technology trees featuring hundreds of upgrades instead, WorldShift allows the players to discover and acquire a vast number of items and powerful relics that they can use to freely change their gameplay and preferred tactics and to attack their enemies. The rest of the Earth is populated by what is known to be the Tribes, successors of the early humans that were affected by the Plague, and the Cult, a mysterious alien race with unknown origins. The human race has developed a new culture and is now living in five shielded mega-cities, struggling to survive from day to day. The remains of the mysterious object, known as Shard Zero, are still spreading its Plague and reshaping the Earth. WorldShift is set thousands of years after those events, when the human civilization is no more than just a fading myth. In the 21st century, a mysterious object lands on Earth ending all known civilization.
