need to massively scale up renewable electricity, with a sixfold increase in our solar and wind electricity production. Fourth, we must make ready the major fl exibility capacity (batteries, hydroelectricity, etc.) that we will need in order to balance our networks. Finally, energy saving and effi ciency will also be essential to achieving our

In order to fully understand how the latest in speed parts work, you first need to understand how an engine works. Most cars as we know them are powered by what is called a 4-stroke engine. A 4-stroke refers to the four strokes in the power cycle; the intake stroke, the compression stroke, the power stroke and the exhaust stroke. We will cover thes...
The block is the main part of the engine that contains the reciprocating components that harness the energy in the gasoline. If you’re looking under the hood, it’s the big piece of metal that’s found in the center of the engine bay that seems to have a whole bunch of other metal, wires and tubes attached to it. The block has circular holes that pis...
Pistons move up and down in the cylinders of the block because a mixture of fuel and air is ignited within the cylinder. The subsequent combustion rapidly expands and pushes the piston down the length of the cylinder bore, away from the cylinder head, and with a lot of pressure. That power produced in one cylinder is multiplied because the combusti...
The pistons are attached to a piece of metal called a connecting rod. The connecting rod’s job is to transfer the force of the pressure shoving the piston down the cylinder bore to the crankshaft or “crank”. Providing the link between the piston and the crank, it is understandable how connecting rods earned their name. The connecting rod is coupled...
The crank in an engine is very similar to a bicycle crank. The up-and-down force of you pedaling is exactly like the up-and-down force of the pistons moving up and down the bore. In a car engine, instead of the energy of your legs pushing on pedals to create the force it’s the combustion in the cylinder and pressure acting on the piston that create...
The cylinder head also contains the intake and exhaust valves. The intake and exhaust valves are metal pieces that resemble golf tees. The valves act as doorways for incoming air and fuel and outgoing exhaust gasses, respectively. During the 4-stroke process, the intake valves open to allow the air/fuel mixture into the combustion chamber then clos...
As mentioned earlier, the cylinder head is a big piece of metal that attaches to the top of the block and covers the cylinders where combustion occurs. Usually constructed from aluminum, the head also contains the spark plugs, valves and the rest of the valvetrain (valve springs, retainers, camshafts). The head(s) have to be torqued down to the blo...
Most modern engines have a dual overhead cam (DOHC) valvetrain which means that the intake and exhaust valves have their own camshafts. The advantage of having separate camshafts is that each cam can be placed very close to the valve, allowing the cam’s lobes to either work directly on the valves or through a very small rocker arm. This reduces the...

ENGIE’s great leap forwards In 10 years, between 2010 and mid-2020, ENGIE’s installed renewable capacity has more than doubled, from 13 GW to 31.1 GW, not to mention the further 5.5 GW currently under construction. ENGIE has turned mature renewable energy sources into the driving force of the energy transition. Two key words: innovation and ...
- Why Commit to Net Zero? As with any strategic endeavor, begin by asking “why?” The answer will likely revolve around opportunities, risks and stakeholder perspectives.
- When Should You Reach Net Zero? The trajectory of your Net Zero initiative should align to a well below 2°C (preferably 1.5°C) science-based trajectory.
- Where Are Your Emissions Boundaries? A credible Net Zero target must include a company’s full carbon footprint. That means developing a complete corporate GHG emissions inventory – incorporating Scope 1, Scope 2, and Scope 3 emissions.
- What's Your Strategy to Achieve Net Zero? Delivering on the Net Zero commitment requires nothing short of an end-to-end transformation at an unprecedented scale and pace.
expensive. As Mathias Lelièvre, CEO of ENGIE Impact, explained, “The intersection of scalability and tailor-made tension is what makes the product management so challenging and key – you need to make trade-off calls all the time.” • Since the BUs were accountable for digital projects, they were reluctant to take on
