Renewable Energy

According to the U.S. Energy Information Administration (EIA), in 2022, about 913 billion kilowatt-hours (kWh) of electricity were generated from renewable energy sources in the United States. This represents about 21.5% of total U.S. electricity generation.

The top three renewable energy sources in the United States in terms of electricity generation in 2022 were:

  • Wind: 435 billion kWh (10.2%)
  • Hydropower: 262 billion kWh (6.2%)
  • Solar: 146 billion kWh (3.4%)

Other renewable energy sources that generated electricity in the United States in 2022 include biomass, geothermal, and ocean energy.

Globally, renewable energy generation has been growing rapidly in recent years. In 2021, renewable electricity generation rose by almost 7%, a record 522 TWh increase. The share of renewables in global electricity generation reached 28.7% in 2021, after modest growth of 0.4 percentage points.

The growth of renewable energy is being driven by a number of factors, including the declining cost of renewable technologies, the increasing demand for clean energy, and the need to reduce greenhouse gas emissions.

As renewable energy continues to grow, it is expected to play an increasingly important role in the global electricity mix. By 2050, it is estimated that renewable energy could account for up to 80% of global electricity generation.

Circular Economy

What is a Circular Economy A circular economy is an economic system aimed at minimizing waste and making the most of resources. It is often contrasted with the traditional linear economy, which has a 'take-make-waste' style of production. In a circular economy, we 'reduce, reuse, and recycle' to keep products, equipment, and infrastructure in use for longer, thus improving the productivity of these resources. Video :   Amsterdam: The green standard of circular economies Circular economies are designed to benefit businesses, society, and the environment. They are restorative and regenerative by design, aiming to keep products, components, and materials at their highest utility and value at all times. The circular economy can be split into two main components: Technical nutrients : These are non-biodegradable materials, such as metals and most plastics. These should be designed and marketed with reuse in mind from the start, so they can be reused continually, thus prevent

EV : Common Terms

  Term Definition AC (Alternating Current) An electric current that periodically reverses direction. In the context of EVs, AC is the type of power supplied by the electric grid and used by Level 1 and Level 2 charging stations. DC (Direct Current) An electric current flowing in one direction only. In the context of EVs, DC is used by fast charging stations to charge a vehicle directly. Level 1 Charging This refers to charging an EV using a 120 volt AC plug (a standard household outlet). It is the slowest form of charging and typically provides 2-5 miles of range per hour of charging. Level 2 Charging This refers to charging an EV using a 240 volt AC source (like a household clothes dryer plug). It is faster than Level 1 charging and typically provides 10-60 miles of range per hour of charging. DC Fast Charging (DCFC) This refers to charging an EV using a DC power source. It is much faster than Level 1 or Level 2 charging and typically provides 60-100 miles of range in 20 minutes of ch

Home Charging 101

  Should You Install an EV Charger at Home? Top Selling Chargers Deciding whether to install an electric vehicle charger in your home is an important consideration if you own or are thinking of buying an EV. Here are some key factors to weigh when making this decision: Benefits of Home EV Charging Convenience - Always have access to charge your EV when needed Cost savings - Can charge during off-peak utility rates Solar integration - Use home solar energy to charge EV Range anxiety reduction - Ability to frequently top off battery Types of EV Charging Stations Level 1 - Slowest, uses 120V outlet Level 2 - Faster, requires 240V outlet Level 3 - Commercial fast charging Installation Factors DIY vs pro install - DIY possible if 240V outlet in place, otherwise use electrician Location - Garage, driveway, exterior of home? Electrical capacity - May need panel upgrade to support charger Hardwired vs plug-in - Hardwired recommended for max speed/safety Cost - $300-$800 for equipment, $200-$4
