Obama Releases US Universal Photovoltaic Action Plan

Abstract On May 9, US President Barack Obama unveiled a comprehensive action plan aimed at accelerating the adoption of energy-efficient technologies, with a strong focus on photovoltaic (solar) power generation. Over 300 companies and public institutions across the United States have joined this initiative, marking a significant step toward a more sustainable energy future. The program aims to install a solar power system capable of meeting the electricity needs of approximately 130,000 households, with a total capacity exceeding 850 MW.

In addition to expanding solar infrastructure, the initiative also targets job creation. By 2020, it is expected to generate around 50,000 new jobs in the solar industry, with a dedicated training program to support workforce development.

President Obama also announced a $2 billion investment to improve the energy efficiency of federal buildings. By integrating smart appliances and energy-saving technologies, the government aims to cut energy costs by an estimated $26 billion over time.

Beyond government efforts, the plan includes a goal to boost energy efficiency in residential, commercial, and industrial sectors by over 20% within the next decade. This will be achieved through stricter energy standards, incentives for green technology, and increased public awareness.

As part of the initiative, companies and organizations are encouraged to adopt energy-saving measures. The total area of buildings achieving energy savings is expected to reach over 90 square kilometers. Residential and utility companies will expand their solar installations, while retail businesses will focus on reducing energy use in stores.

To support these goals, the financial sector is also increasing its commitment to renewable energy. For example, Goldman Sachs has pledged to invest $10 billion in clean energy projects by 2021.

Since Obama took office, the U.S. solar power capacity has grown tenfold, while wind power has tripled. The cost of solar systems has dropped by about 50% over the past three years, making it more accessible than ever. As a result, in 2013, solar energy accounted for about 25% of total power generation in the U.S., ranking second only to natural gas.

Several major corporations have also announced their own sustainability initiatives. Apple and Yahoo are planning to install solar power systems at their facilities, while Google has committed $1 million to support breakthroughs in next-generation power conversion systems (PCS). These efforts reflect a growing corporate commitment to clean energy and environmental responsibility.

Gully Gratings

Gully gratings are metal or plastic grates that are used to cover and protect gully openings in the ground. These openings are typically found along roadsides, sidewalks, or other areas where water runoff needs to be collected and directed to a drainage system.

Gully gratings are designed to allow water to flow through while preventing larger debris, such as leaves, trash, or rocks, from entering the drainage system. They are usually made from durable materials like cast iron or galvanized steel to withstand heavy loads and resist corrosion.

In addition to their functional purpose, ductile gartings, cast iron gratings are also provide a safety measure by preventing pedestrians or vehicles from accidentally falling into the gully. They are often designed with anti-slip surfaces or raised edges to enhance traction and prevent accidents.

Gully gratings come in various shapes and sizes to accommodate different gully openings and flow rates. They can be square, rectangular, or circular in shape, and may have different patterns or designs on their surface for aesthetic purposes.

Regular maintenance of gully gratings is important to ensure they remain clear of debris and allow for proper water flow. This may involve periodic cleaning or removal of any obstructions that may accumulate over time.

Overall, gully gratings play a crucial role in managing surface water runoff and preventing drainage system blockages. They provide both functional and safety benefits, making them an essential component of urban infrastructure.
