It is the energy obtained from hydroelectric power plants; on rivers, tidal, etc.
this means that the world of the dy is the world of the time of the world
hydroenergy
Let falling/running water turn a water wheel, hydroenergy to mechanical energy.
Examples: methane, petrol, gold, soil for the agriculture, hydroenergy, mineral waters, forests, thermal waters, marble, other natural building materials etc.
1. Carpathians Mountains, rivers, lakes, hills, plains, caves. 2. Examples: methane, petrol, gold, soil for the agriculture, hydroenergy, mineral waters, forests, thermal waters, marble, other natural building materials etc. 3. The Romanian language; a minority spoke the Hungarian language.
A Natural resource is something nature gave us. Some natural resources that were found in Transylvania are water, trees, mountains and soil. But that is not all of them.Examples: methane, petrol, gold, soil for the agriculture, hydroenergy, mineral waters, forests, thermal waters, marble, other natural building materials etc.soils for agriculture, forests, plains, mining (coal, methane gas, gold, silver, uranium, mercury, lead, zinc, bismuth, tellure, cadmium, building stones, sand, bauxite, etc.), mineral waters, etcwood, methane gas, hydroelectric power, marble
All forms of energy on earth other than nuclear energy, gravitational energy, and electromagnetic energy originate from the sun. The sun is a partial source of some of these on earth as well, but not all of them. Of the forms of energy obtained from the sun: * solar energy is the most direct, and is energy radiated to the earth from the sun * wind energy is primarily caused by thermal effects from the heat radiated from the sun * hydroenergy (from hydropower stations on rivers) is from potential energy created by the evaporation of water (by the sun) that then rains into catchments for hydropower dams * wave energy is created by thermal effects from the sun and the earths core and to a lesser degree gravitational effects from the earth, sun and moon * biological sources of energy are from plants that use the energy from the sun, water and CO2 to store energy by creating glucose and then more complex carbohydrates. All biological sources of energy are dependant on this process. Animals get their energy from these carbohydrates or from other animals that have eaten carbohydrates. Even the oil extracted from the earth for energy is biological in origin and predominantly comes from ancient plants that have been condensed through geological processes into a concentrated energy rich form. Even other sources of energy, such as chemical reactions, require some energy to get them started, or to get the materials brought into a condition where they will react, and the origin of this is almost always the sun.
Geothermal energy sources depend on primeval heat from the Earth's core.This is mainly derived from radioactive decay in the Earth's core, with a small contribution from gravity pressure.Similarly, Nuclear Reactors do not depend on the Sun for their energy.And one day we hope, the nuclear fusion problem will be cracked.And to a small extent, the electrical energy developed in a battery does not depend on the Sun, but most of the energy needed to make the battery would probably have come from a solar source.and the solar source is like solar pannels so if the solar energy depends on the sun geothermal energy does too.
