Why solar energy is not widely used?

The available power grid infrastructure was built to work with consistent power generation levels and these grids may not be able to cope with the inconsistency of solar energy. Another factor that reduces the competitiveness of solar energy is how often electricity is produced; also known as its capacity factor.

Over the last few years, the world has been shifting its focus to renewable energy in an effort to mitigate the effects of climate change. Major components of the renewable energy transition have been solar panels and solar farms. The utility and resourcefulness of these solar panels have been much talked about; and the panels have been portrayed as the gateway out of conventional energy. For this much talk about their benefits, it is important to discuss why they are not as common as they should be. Solar panels, which are sometimes referred to as photovoltaic (PV) panels, are panels that consist of solar cells that are used to collect and convert sunlight into electricity for power generation. These solar cells are made up of silicon semiconductors consisting of a negative layer and a positive layer opposite to each other. These layers create an electric field and generate direct current (DC) electricity. In domestic applications, solar panels can achieve around 20% solar efficiency, meaning that it can convert 20% of the sunlight it collects into usable electricity. Solar panels have numerous advantages along with some disadvantages. The biggest advantage of solar panels is the fact that they are clean and carbon free; they do not contribute to greenhouse gas emissions. Another major advantage of solar energy is that it is renewable; this form of energy is sustainable and, quite literally, endless. Other advantages of solar panels include, but are not limited to, their diverse application and their low maintenance costs. The installation of solar panels is also creating new jobs in the renewable energy sector. On the other hand, one of the disadvantages of solar panels is that solar panels are weather dependent. However, most panels come equipped with batteries that store electricity for later use. Another drawback for solar panels is that, due to their low efficiency, they require large areas for installation; however, with advancing technology in this field, solar efficiency is expected to increase in the coming years.

What is the 4 retirement rule?

One frequently used rule of thumb for retirement spending is known as the 4% rule. It's relatively simple: You add up all of your investments, and withdraw 4% of that total during your first year of retirement.

schwab.com - Beyond the 4% Rule: How Much Can You Spend in Retirement?

You've worked hard to save for retirement, and now you're ready to turn your savings into a paycheck. But how much can you afford to withdraw from savings and spend? If you spend too much, you risk being left with a shortfall later in retirement. But if you spend too little, you may not enjoy the retirement you envisioned. One frequently used rule of thumb for retirement spending is known as the 4% rule. It's relatively simple: You add up all of your investments, and withdraw 4% of that total during your first year of retirement. In subsequent years, you adjust the dollar amount you withdraw to account for inflation. By following this formula, you should have a very high probability of not outliving your money during a 30-year retirement, according to the rule. For example, let's say your portfolio at retirement totals $1 million. You would withdraw $40,000 in your first year of retirement. If the cost of living rises 2% that year, you would give yourself a 2% raise the following year, withdrawing $40,800, and so on for the next 30 years.
