Reflections on energy: Towards a new system

REthinking Energy. reflect on energy renewable

A whole series of circumstances combined between the economy, demographic movements, change climate and technology has launched a widespread transformation of the energy system overall.

The demand for energy services will undoubtedly is increasing considerably , the population increases with a tendency to concentrate in cities and with new demands that require a greater demand for energy. At the same time, there is a greater consensus on the dangers posed by climate change that has led to governments around the world to find ways to generate that energy while minimizing the greenhouse gas emissions and other impacts environmental.

Increasingly, renewable energies are seen as as the best solution for a population world market that demands affordable access to electricity while reducing the need for fuels toxic fossils that are causing unsustainable levels in greenhouse gas emissions.

That is the underlying message that we can find in the new report – Reflections on the energy: towards a new energy system food – published this week by the International Energy Agency Renewables (IRENA) that reveals more than one interesting point about a sector that is totally up.

Why is the cost of renewable energy more cheap?

Large-scale hydroelectric, geothermal, and biomass has been competitive, but for many years the wind and solar power have struggled to compete with coal, oil or natural gas without obtaining clear results in regarding the cost of energy. However, during the last decade and particularly during the last five years, the image has changed drastically determined by several factors:

• The technologies used in the energy renewables are much more efficient , each increasingly capable of generating energy even in conditions less optimal, with little wind, low speeds or low solar irradiation.
• The energy storage technologies they are improving rapidly.
• Policies from Europe or the United States , or new industrial powers such as China have caused a collapse in energy prices. Energy Solar-photovoltaic have fallen in price by 80% since 2008, with a downward trend in the coming years.
• The cost of turbines has fallen almost 30% since 2008 causing – among other factors – that the cost of wind electricity falls by 18% since 2009.
• More consumer markets . More than 100 Countries – with needs, innovation opportunities, research and economic investments that attract new companies and competitors.

In short, the renewable energy capacity in the whole world has grown 85% in the last 10 years, reaching 1,700 GW in 2013, with renewable energies today they constitute 30% of all installed power.

The challenge has gone from…. If renewable energy can feed a modern lifestyle – which now we know you can – to the best way to finance and accelerate its deployment.

What are the biggest benefits of energy renewable?

There is growing evidence that renewable energy has a positive ripple effect throughout society, advancing at the same time in an economic, social and environmental

• Renewable energies are good for the economy of a country . A recent Japanese study, found that the benefits were 2-3 times greater than the costs – including savings on imports of fossil fuels, CO2 emissions and their economic repercussions.
• Although it may seem unbelievable, renewables in Spain prevented the importation of 2.8 Billion in fossil fuel in the year 2010 .
• Renewables can also bring energy electricity to people who are currently left out of the network, promoting
• They do not deplete natural resources.
• Avoid unnecessary risks of ecological disasters
• Creation of employment. 6.5 million jobs direct and indirect all over the world , as we can see in the picture.
• Offer a route to reduce greenhouse gas emissions greenhouse effect, one of the main causes of global warming.

“We know that currently not only with the renewable energy can meet the growing worldwide demand, but we recognize that you can do it cheaper, while helping to limit global warming global in less than 2 degrees Celsius – the very tipping point cited by climate change – taking into account that the power generation by 2030 will increase by 70%, adds the report”

“There is a growing concern about the health impacts from burning fuels fossils , according to the report, adding that the Agency for United States Environmental Protection recently has discovered that problems with caused by by fuels f or nationally cost between $362 billion and $887 billion annually.”

According to the General Director of IREMA ( Adnan Z. Amin) In the presentation of the report … “The convergence of social, economic and environmental forces are transforming the global energy system as we know, but if we continue on the current path, feeding our economies with an outdated way of thinking and acting, we will not be able to avoid the most serious impacts of the climate change."

Undoubtedly the report of 90 and something pages does not stay just with a little introduction.
