Climate change crisis and renewable energy - Coggle Diagram

- - - - Wind power
        
        Wind power harnesses the kinetic energy of moving air through the use of huge wind turbines located on land, offshore or in freshwater.
        
        Although average wind speeds vary markedly depending on each location, the global technical potential for wind power exceeds the global production of electrical power, also taking into account the potential in most regions of the planet to allow significant deployment. of this wind-based energy.
        
        The generation of wind energy in aquatic areas represents an outstanding potential.
      - Of all the sources of energy, solar energy is the most abundant and, in addition, it can also be obtained even with cloudy skies.
        
        Solar technologies can produce heat, cooling, daylight, electricity, and also fuels for a multitude of applications. Although not all countries are equally favored by sunlight, we know that in any country a significant contribution of solar energy to all its energy sources would be viable.
    - - Geothermal energy uses the thermal energy available from the interior of the Earth. Deposits with these high enough temperatures and naturally permeable are called hydrothermal deposits, while deposits with sufficient heat, but using means of hydraulic stimulation, are called enhanced geothermal systems.
        
        This technology, which consists of the generation of electricity through geothermal deposits, is already mature and reliable, and has been in use for more than 100 years.
    - - Hydroelectric power uses the energy produced by the movement of water when it rises or falls sharply. It can be generated from reservoirs and rivers.
        
        Hydroelectric reservoirs usually have multiple applications, producing drinking water, water for irrigation, flood and drought control, navigation services and also this energy supply that we indicate.
        
        Hydroelectric power is currently the largest source of renewable energy in the electricity sector. The infrastructure needed to create hydroelectricity can also change ecosystems in very negative ways.
    - - Ocean energy derives from technologies that use the thermal energies of seawater, waves or water currents, for example, to produce electricity or heat.
    - - Bioenergy is produced from various organic materials, called biomass, such as wood, coal, dung, and other fertilizers used for heat and electricity production, and agricultural crops for liquid biofuels. Modern biomass systems incorporate specific trees or crops, residues from agriculture or forest environments, as well as organic waste streams.
        
        However, bioenergy should only be applied in certain situations as its potentially negative environmental impacts are related to a large-scale increase in bioenergy and forest plantations, leading to deforestation and land use change. of Earth.
- - - - According to the latest UN reports, thousands of scientists and government reviewers agreed that limiting global temperature rise to no more than 1.5°C would help us avoid the worst climate impacts and maintain a livable climate. However, current policies point to a temperature increase of 2.8°C by the end of the century.
        The emissions that cause climate change come from all parts of the world and affect everyone, but some countries generate much more than others.
      - Causes and effects
        
        Fossil fuels are by far the biggest contributor to global climate change, accounting for more than 75% of global greenhouse gas emissions and almost 90% of all carbon dioxide emissions.
