The transition from fossil fuels
Half of society’s overall energy usage is heat. Today the largest portion of the energy consumption comes from coal and oil. At the same time every hour of solar radiation provides enough energy to to satisfy global energy needs for an entire year.
The world’s energy usage is rapidly rising as living standards increase for billions of people in the developing world. Fossil fuels are becoming more and more expensive, and as more countries fulfill their commitments for reducing carbon dioxide emissions, the share of renewable energy must increase to represent the majority of the world’s energy supply within a few decades.
There are large amounts of money being invested in new sources of energy: an estimated € 500 per person and year over the coming 20 years. In Europe, with 500 million inhabitants, the volume of investment is € 50 billion annually. Larger properties and industries will get a large portion of their energy from self-sustaining systems on their own roof in order to meet the transition.
Solar concentrators replace costly fuels.
The EU’s new building directives require “near-zero energy” for all new and renovated properties as of 2021, which in most cases means that the property will be self-sufficient with solar collectors on the roof and facades. In Spain and parts of Italy, legislation has already passed that mandates installation of solar collectors for new houses and buildings.
In the industry, energy-demanding processes that currently run on oil or gas will undergo fundamental efficiency measures. The energy that is needed for production will come in part from solar energy systems on the roof of the factory. Solar concentrators can provide both heat and steam that can directly replace costly fuel.
Heat is half
We need electricity, heat and transportation to run our society. Together they make up our total energy demand and the largest part of it is the heat.
Half of the overall energy usage is heat. Electricity and transportation splits the other half. Heat is used to make our everyday products, such as clothes, dairy products, drinks and food. Solar collectors like Absolicon T160 can produce energy needed to meet the heat demand with zero emissions. The sun shines for free, the heat losses are very small at daytime and the heat can be stored for when the sun is down.
