Three reasons the future is all electric energy central electricity lesson plans 4th grade


We live today in an energy system which was discovered during the second industrial revolution. This energy system shale gas in spanish consumes around 150,000TWh of energy yearly, with 80 per cent of it coming from fossil fuels (oil, natural gas, coal). A century ago, this was 10 times less, an indication of the tremendous economic developments that this new energy system has enabled. Today, a large chunk (40 per cent) of this primary energy is used to produce electricity, the rest being transformed and refined.

This energy system shows major limitations as the world’s development accelerates at an ever-faster pace. First, it is heavily chapter 7 electricity test carbonized. Today, energy represents around 80 per cent of the total CO2 emissions, an issue which has taken centre-stage in recent years. It also creates significant dependencies, as fossil fuel reserves are not equally distributed across the globe. Finally, it is massively inefficient. 60 per cent of the fossil fuels extracted are wasted, with half of it being lost in the production of electricity, and another half from the actual use of these fuels in inefficient combustion engines or heating systems.

3. The migration towards an all-electric renewable based system could nearly double the overall energy system efficiency, through the combination of a power sector relying on renewable energies and electrification of major uses c gastronomie mariage of alternative energies (transportation, heating, etc. – traditionally 2 to 5 times less efficient depending on the application).

Numerous studies have shown that the transition to a renewable-based energy system would not significantly increase the overall current capital electricity trading hubs expenses dedicated to energy. In addition, renewable-based electricity production has very low operating expenses (operation, maintenance and fuel costs), typically ranging 2 to 4 times lower than traditional power technologies.

This new all-electric renewable-based energy paradigm therefore has the potential to make energy more accessible – fostering economic development, as well as new uses of energy which were unimaginable before. Let’s pick just one example – the accelerated development of digital technologies which are creating a new surge for energy demand, as discussed in one of my recent blogs.

Many large organizations in the world are today converging towards this probable future. BNEF has estimated that by 2040 50 per cent gasco abu dhabi contact of global power capacity could already be of renewable sources, while electric vehicles (EVs) could represent over 50 per cent of total annual car sales. The Energy Transition Commission has estimated that power decarbonization combined with electrification could lead to a 25 per cent reduction in CO2 emissions by 2040. Shell, has recently presented a likely future (Sky gas x dosage for dogs scenario) where net CO2 emissions could be zeroed by 2070, with electricity (80 per cent renewable) to represent close to 60 per cent of the total energy mix (vs 20 per cent today).

Many companies around the world have acknowledged this and are taking the necessary steps to be ahead on the curve. One example is Hewlett-Packard which chose Schneider Electric to help them reach their goal of reducing greenhouse gas emissions by 40 per cent from 2010 to 2020. HP now can power 100 per cent of its Texas-based data center operations with renewable energy.

Take the example of Fairfield static electricity online games, Connecticut. The town uses a microgrid with the ability to island or disconnect itself from the central grid if utility power is lost in an emergency. This gives the coastal town 120 per cent of its peak demand power during an energy crisis or extreme weather event. Demand-side is the new frontier where the transition will accelerate or stumble.
