Apple Inc. is a multinational technology company headquartered in Cupertino, California, United States of America. It is one of the largest mobile phone manufacturers in the world, with its flagship product being the iPhone. The company was founded in 1976 by Steve Jobs, Steve Wozniak, and Ronald Wayne, and has since grown to become one of the most valuable companies in the world.

Apple has a strong commitment to sustainability and has made significant efforts towards decarbonisation and the use of renewable energy. The company has set a goal to become carbon neutral by 2030, which means that it will eliminate its carbon footprint entirely. This is a significant challenge, given that Apple's products are energy-intensive to manufacture, and its data centers consume a significant amount of energy.

To achieve its decarbonisation goal, Apple has implemented a range of initiatives, including the use of renewable energy, energy efficiency measures, and the adoption of green technologies. The company has invested heavily in renewable energy, with a particular focus on solar power. Apple has built several solar farms in the United States, including a 1300-acre solar farm in California, which is one of the largest in the world. The company has also invested in wind power, with a 200-megawatt wind farm in Texas.

In addition to investing in renewable energy, Apple has also implemented energy efficiency measures to reduce its energy consumption. The company has designed its products to be more energy-efficient, with features such as low-power mode and automatic screen dimming. Apple has also implemented energy-efficient lighting and HVAC systems in its offices and data centers.

To further its commitment to renewable energy, Apple has also entered into corporate power purchase agreements (PPAs). These agreements allow the company to purchase renewable energy directly from a renewable energy project. Apple has signed several PPAs, including a 130-megawatt solar PPA in California and a 200-megawatt wind PPA in Oregon.

Apple has also made significant efforts to reduce its corporate energy consumption. The company has implemented a range of energy-saving measures in its offices and data centers, including the use of energy-efficient lighting and HVAC systems, and the adoption of virtualization technologies to reduce the number of physical servers required.

Overall, Apple's commitment to decarbonisation and the use of renewable energy is commendable. The company has made significant investments in renewable energy, implemented energy efficiency measures, and entered into corporate PPAs to further its commitment to renewable energy. Apple's efforts towards sustainability are a model for other companies in the mobile phone sector and beyond.
