Climate change constitutes the greatest environmental threat ever suffered by humanity.
Climate change is the evil of our time and its consequences can be devastating if we do not drastically reduce our dependence on fossil fuels and greenhouse gas emissions. In fact, the impacts of climate change are already perceptible and are evidenced by data such as:
- The global average temperature has already risen 1.1 ° C since pre-industrial times
- At the period 2015-2019, according to the World Meteorological Organization (WMO), has been the warmest five-year period ever recorded
- The rate of rise in sea level has risen to 5 mm per year in the five-year period 2014 -2019
But today we are also seeing the economic and social impacts, which will be increasingly serious, such as:
- Damage to crops and food production
- Health risks
- Extreme weather events, such as damage, storms and hurricanes
In the worst probable scenarios that the experts reflect, the temperature increase could reach 4.8 ºC by the end of the century. Climate change is a global problem that reaches an environmental, political, economic and social perspective in which the worst forecasts also imply huge economic losses. And it is that the longer we take to act, the much higher will be the investments to adapt to the increase in temperature.
79% of greenhouse gas emissions in the European Union are due to the burning of fuels for energy or transport uses, according to Eurostat data.
Still in 2017, 91% of the energy used in Spain came from non-renewable sources such as fossil fuels or nuclear energy. In fact, Spain, along with five other countries of the European Union, accumulates around 70% of all greenhouse gases on the continent.
The energy sector, due to the use of dirty energy sources – oil, coal and gas – is one of the biggest contributors to global warming. Some 90 companies are responsible for almost two-thirds of global emissions. In Spain, the large electricity companies continue to generate a large part of their electricity using non-renewable sources, which is why we are working to change this unsustainable model and accelerate the transition to an efficient, intelligent energy system, 100% renewable and democratic.
The energy revolution in the hands of the citizens is the way: with renewable energies it will be possible to mitigate the effects of climate change and achieve energy efficiency that will generate jobs and reduce electricity costs. We need to do away with polluting fuels and nuclear energy and increase citizen participation so that they benefit from the renewable transition.
It is a model in which control over energy is not a privilege of large energy companies, but a citizen’s right, where each household could be the owner of its energy, which can produce, consume, accumulate and exchange at its own right value and in freedom.
This energy transition that is already taking place in many parts of the world, in Spain finally begins to take off after the repeal of the “Sun Tax” (Royal Decree-Law 15/2018, of October 5, on urgent measures for the energy transition and the consumer protection) in 2018 and its subsequent regulatory development (Royal Decree 244/2019, of April 5, which regulates the administrative, technical and economic conditions of self-consumption of electricity), in which self-consumption is developed shared, individual and proximity and the right to remuneration of surpluses is recognized.
It is the obligation of all governments to promote it, thus prioritizing the general interest, the fight against climate change and the abandonment of non clean energy.
Within this strategy, where any source of renewable energy must be used to contribute to the energy mix, hydraulic turbines play an important role. To date, hydroelectric turbines have only been installed in large dams or reservoirs, with the capacity to generate high powers in the order of megawatts.
However, the installation of so-called “pumps used as turbines” (or PATs) has recently spread. This technology is based on the use of a conventional pump in reverse mode as a turbine for generating electrical energy.
In this way, it is currently possible to use a small hydraulic turbine to generate energy on a small scale for potable water or irrigation networks. These are small microturbines of less than 100kw of power but with multiple possibilities of installation in water networks (drinking water tanks, irrigation basins, pressure reducing valves, load break boxes, etc.).
It is therefore a profitable and efficient opportunity for drinking water distribution companies or irrigation communities to generate their own green energy, as well as to contribute to a decentralized model of energy production, reducing losses due to the transmission of the electricity system.
On the other hand, these small hydraulic turbines can also generate energy for private use in a home. Therefore, citizens currently have a wide range of possibilities to generate their own energy (solar, wind, mini hydraulic turbines, etc.)
The total commitment to renewable energy is not only the safest option for the planet, but also for the economy. A model based mainly on renewable energies (solar, wind, mini-hydraulic energy, etc.) and energy savings would create more than 3 million jobs in the Spanish State, increase GDP by two points per year and reduce the energy bill by 34 % compared to 2012, all of this would be achieved by 2030.
What can you do?
Take action with your consumption! By adopting some simple energy efficiency measures in your home, you will save money and contribute to the fight against climate change. Here we propose some:
- Lower your electricity bill lowering your hired power
- Put your green electron, produce your own energy
- Acquire more energy efficient appliances
- Use LED bulbs and lamps
- Avoid leaving chargers and transformers plugged in
- Create your own energy project
