The percentage completed each year if the processing speed doubles every 2 years is:

2002-2012 = 2.44%
2013 = 0.53%
2014 = 0.75%
2015 = 1.06%
2016 = 1.5%
2017 = 2.12%
2018 = 3%
2019 = 4.24%
2020 = 6%
2021 = 8.48%
2022 = 12%
2023 = 16.96%
2024 = 24%
2025 = 33.92%
2026 = 48%
2027 = 67.84%
2028 = 96%

We will reach 10% completion in 2018 and 100% in 2025. Assuming that 200 people run distributed.net using 200 watts at 10 cents per kilowatt hour, the power cost is $35,040 per year. The electricity donated to reach 100% in 23 years will cost the participants $805,920.

If we had started the project in 2020, we would still reach 100% in 2025, but we would have saved $595,680! If we wait until 2020 now, we will still save $245,280.
